  1. Brian - I would check 3 things. The oil is on top of the block so the only ways I am aware of that it could get up there, are: 1) check the AOS J tube as is enters the throttle body, if the AOS has failed and is pumping oil and the J-tube seal is bad that would put oil on top of the block. 2) check the oil filler tube for leaks on the lower section, esp as it enters the block under and just fore of the air intake cross connect between plenums. 3) check the oil cooler to the driver side of the block under the air intake pipe that runs from the filert box to the throttle body for failure. I'm just an amature, maybe some of the more experienced guys can help too?
  2. Sorry for the confusion - I installed a new MAF, the good clean was refering to the TB and intake system after the AOS was letting out........ So far the only CEL code i have thrown is a P0430 which is either a bad O2 or a bad Cat.....i'll get to that later!
  3. Well good luck, my 1126, 1128 and 1130 codes were solved by replacing the oil tube, MAF and a good clean! Last night i went for a 90min drive North of Dallas, and all the hard work was worth it! :jump:
  4. Dale - i replaced my fuel cap as a preventative measure with a new one when I had the fuel pump changed out (just like other seals, the rubber degrades with age). I think it was 12 bucks or something like that from Pelican Parts.
  5. I'm not sure about the 'gunk' at the filler cap (maybe mixing coolant but i'm no expert) but I recently went through similar codes - see this thread: I also had a 'hissing' noise - checked all the vaccum lines, took apart and cleaned the TB and intake, new AOS and MAF and eventually found the hissing was a split oil filler tube....was pretty loud. Another good couple of tricks for finding an air leak ar to spray Carb cleaner (careful, it flamable so do this at your own risk) on the intake pipe joints etc, if there is a leak the engine will rev up, or take a length of hose pipe (say 3-4 ft), and use it like a stethescope.....sounds dumb but its how i found the leak on the oil intake! :rolleyes:
  6. Very common to throw codes with cracked or leaking oil filler tube. It is best if replaced rather than taped. There are three tubes that connect from the trunk to the center front top of the enginge. The leak is usually between the 1st and 2nd joint, which is next to the AOS and under the air tubes and throttle body. Be careful if you attempt to remove and replace the 1st and 2nd tube because the 3rd tube is connected to the engine by a couple of thin plastic ears and they can break off. Ask me how I know:( Here is a link to a recent Forum Discussion. PRESS HERE Thanks - I would not have linked the oil fller tube to this. Good to know its fairly common to get these codes due to this issue. I replaced the AOS etc, and I could hear a strong hissing, checked all the vacuum pipes and lintake for leaks with carb cleaner, but could not pin it down. I hear you on the lower oil filler tube ears, see this thread - mine was held on with only one bolt too - but solid with no cracks. I taped a 'cap' to the top of the lower tube, and hey-presto no leak so it must be in the middle tube. Oil filler cap seal looks good and idle didn't change when i opened the cap. I have the middle tube section on order - looks like a PITA to install the upper joint though!
  7. Well - first test run with the new MAF, new ICV, cleaned TB, new AOS and (temp) fix to the leaking air intake. 1) Idle is smooth cold and hot. 2) Temp ran slightly cooler - would a rich mixture cause the engine to run hotter - i guess it would, more gas and all? 3) Less of a 'gas' smell from the exhaust, so i guess its not thinking its running lean anymore? Can any of the experts on here explian the connection between Crank-Case Vacuum leaks and the fuel air mixture / MAF issues? FIngers crossied the dreaded CEL stays off!
  8. Leaking Oil Filler Tube! Ok, so I removed the filler tube at the joint below the AOS J tube, placed a Gator Aid bottle cap over the reming finnet tube, taped it with duct tape and hey presto.....hissing sound gone, engine idling like a sweet Prosche should! So my question, would a leak in the Oil intake tube, I.e crankcase vacuum leak have caused my CEL codes? I also just fitted a new Bosch MAF.
  9. Yes, that 2nd bolt is a bear! I didn't have a swivle joint for my rench and was in no mood to go out and get one by this point :cursing: so i took an old 10mm socket, and a long, large flat head screw driver that i happened to have and hammered into the top of the 10mm socket, this gave me a 'socket' thin enough to get a good angle on the 2nd bolt past the alternator.....There's just not enough room to get your hand down there with the 3rd section of tube in Dale. Only make a 2mm cut, not much wider than the blade, and use a washer on the 10mm bolt. Of course, Kbrandsma's way is much less barn-yard! And should probably take preference over my fix! Though the tube isn't under any pressure / load.
  10. Well, i tested the new ICV, resistance 16.9ohms, I also rested the 'old' ICV, resistance also 16.9 ohms. the old one made a buzzing sound with the ignition turned on. Will havr to see how the new one does, waiting for the new MAF before i take it on a test run...... wiring looks ok, hope its not the DME control module on the way out <_<
  11. Dale - i did not remove the intake plenums, just the connecting intake tube and rubber gaskets - be-sure to replace the two small vacuum hoses on the cabin side of these! I didn't spot them at first. Like I said the one bolt is obscured by the alternator - i got around thi by starting the bolt in the engine block thread before i put the oil filler tube back in, then with a small slot cut in the lug on the filler tube, slipped it over the bolt - I am not sure if removing the inspection panel would help, may do, or you may need to pull the alternator. AOS was a PITA but worth it. I changed the spring loaded hose clamp for a screw typ on the bottom of the bellows, much easier. if you clean off the metal to which the bellows mates, smeer a little engine oil on it, the bellows literaly should slip on by itself....did for me anyway. I took a camera to check that it was seated flush then tightend it up. The bolts to hold the AOS in place are a little tight to get to, and as you said you can't really see them! I lay on my back, head behind the wheel assembly, put a couple of flaslights around to light up the area. Two pics attached, one is the best shot i have of the oil tube with the central intake tube removed, other is the bellows on the new AOS.....andd the oil gunk from the last one leaking! Need to clean that up!
  12. Dale - I did just what you are considering over the past weekend, I tooo have a leak somewhere, so last weekend i took the intake tube (between the intake plenums) and throttle body off for a good clean, and also changed out my AOS. While I was in there the oil filler tube seemed loose. As stated above, its in 3 parts, 1st from the filler cap to the void (between the trunk and the visible engine bay), 2nd a mid section that ends with a hose clamp located roughly under the J tube from the AOS to the intake, and the third from that joint into the top of the engine case. Turned out only one of the two bolts (T10) that secure the filler tube to the engine case were in place on mine. One thing to note, if you plan to take the oil filler tube out of the engine block, one of the bolts (the missing) one is obstructed by the the alternator (or starter motor, can't recall now) - to 'replace' the missing bolt i cut a slot in the locating tab so i could slip it over the bolt (and washer), I was then able to tighten it from the engine bay with a long extension on the rachet. Its a little tight in there, but not too bad.
  13. Ben - hopefully you have found the fault by now..... I had a similar noise after my transmission was replaced.....turned out the park brake cable to the passenger side had shifted, it was against the inner rim of the wheel - as the wheel spun, the balance weight on the inside of the inner rim was hitting the cable.....click, click, click..... Noise would 'stop' above 5-10mph.. Andy
  14. Right, well i'll check it tomorrow, just to be sure. That was my next question, is it a commmon failure on older cars! Seems I read that the solenoid just gets weak over time somewhere. Thanks for your advice Loren. Andy
  15. Hey thanks for getting back to me Loren. I just checked the ICV wiring harnesses and the wires I could see before they went into the sleeves. They all look fine. Is there anyway I can test the ICV or is it just a case of replacing it?
  16. Ok, I did a search on the P1551 & P1514 codes and came across a post from 2005..... the last reply was from Loren, sounds like the issue i have as mine is idling rough but runs well warmed up..... Posted October 22, 2005 - 01:55 PM Kyrak, on Oct 22 2005, 12:19 PM, said: Just when you thought it was safe to go back in the Boxster....IT'S BACK! P1514 and P1551 again. Not sure where to go from here. Any advice? ow would i check the coil voltage? Could i have damaged the ICV when cleaning it? Kyrak Both of those point to an open idle control valve. Have you checked the voltage to the coil of the valve?
  17. Ok guys, I've got some codes for you if you can shed some light on them! P0102, P1124 and P1126 as previously reported are still there. I have a new MAF on order which I am hoping will nail these. I stripped the intake, cleaned the TB and replaced the AOS over the weekend. While doing this I checked all the hoses I could find, no leaks, but it sure sounds loud around the TB, like rushing air, normal? I've been advised to spray carb cleaner on all the intake and vac hoses by my tech to try and find the leak. NEW CODES - P0150 (O2 Sensor, maybe related to a failing MAF?), P1551 (IACV make winding) and P1514 (IACV Break Winding) - can anyone shed any light on these. Engine is rough when cold, better when warm. runs great. I'd really apreciate any help you can offer chaps!
  18. Ok, so after all that - no smoke :clapping: :cursing: but its still running rough on idle and i can def hear a 'hissing' sound from somewhere near the top of the engine..... the vid link to you tube is the best i can do, if you listen, you can here the idle fluctuating, and a 'hissing' esp when the camera is back from the engine a bit. I checked all the air hoses etc, nothing looked loose, cracked or split. Any ideas? I'd really apreacite some expertise guys! Thanks Been in the garage for 10 hours now......time to call it a day!
  19. I found it useful to use a tie-rap to hold the throttle plate open so i could clean it easily. I used CRC Lectra-Motive per Pedro's Garage advice.
  20. The more you do the more you find!! Decides as i was in the intake area looking for leaks to go ahead and replace the AOS as a precaution, car has never smoked other than on start up. So - I ran the engine to re-fill the coolant, see other post on that (coolant cap failure) and she started to smoke, not real bad but enough! So i started to dimantle the Throttle body, and intakes, and this is what I found (aside from the fact that only 2 of the horizontal bolts attaching it to the intake manifold were there :censored: ) second picture is the tube between the intake manifolds (btw if you're taking it off, be careful as it has two vacuum pipes attached to the front of it) I am going to take the manifolds off, clean them both and all the other air intake pipes engine side of the throttle body, clean the J-tube from the AOS, replace the AOS and then put it all back together. I had the spark plugs changed when it was in with an indi 4 weeks ago (I guess they either looked ok or he didn't realize what the crud on them could have meant :censored: ) Any advise would be awesome, do you gys think I am on the right track here? Andy
  21. Thanks Loren, I've cleaned it, and checked the connections and cables visually, I don;t havr the special tool so will skip it. If the fault persits i'll pop in a new MAF once i've found the air intake leaks...........
  22. Can anyone suggest ways to test for ground or an open circuit on the MAF with a multimeter?
  23. Thanks Loren - that puts my mind at rest. Wasn't as bad as I thought to drain the old fluid.
  24. just drained the coolant following the pelican parts guide, new cap and 3gal of Porsche OEM coolant on the way (thanks to this forum....I had 5gal of O'reiley coolant ready to go......but really don't need a jelly soup on my hands right now!!!). Coolant came out a brownish green, thought oil at first but could not see or smell any in there, so I assume its rust from being in there for 14yrs? Pic attached if anyone has seen old coolant before and can confirm the color of 14yr old Porsche coolant! Thanks Andy
  25. Man - a sad day, I know how you feel, mine looked almost exactly the same 4 weeks ago with Transmission fluid trickling down the flat bed (not terminal, since made a nearly full recovery)........Only the good die young!
