Engine Rattle

[alstarz88]

Hi

Hope you can help.

I started a thread for this a couple of days ago but in the wrong place making it hard to find.

I will start from the beginning my car is a 98 2.5 originally and has now been upgraded to a 2002 3.2S

the engine came from ebay supposedly in full working order

a wiring loom also from ebay

alarm ecu and transponder also from ebay

then odometer, abs, AC controller, seat belts, throttle pedal from local supplier

after some slight modifications to engine loom (wires in wrong place or missing) the engine fired up and all codes were deleted

now there is this rattle like a loose heat shield coming from the engine. all heat shields checked and fine it appears to be coming from left bank of engine.

I have video'd it to try and capture the sound I am pretty sure the engine is going to have to come out but I would like your input to localize the problem

Any pointers will help

Hard to say, but it seems more than a loose heat shield to me. I would start with rotating the crankshaft manually and good listen where the noise is coming from, and feel at the same time, if the crankshaft turns smoothly without any resistance on the full rotation.

Hi

I have an update I have started dis assembling the car to take the engine out and whilst disassembling the exhaust system i have noticed alot of oil it can practically be poured out of it

I suggest you inspect the IMS brng for wear. I had one that sounded very similar and the brng was coming apart.

[alstarz88]

how do you remove the bearing

[wvicary]

Search the site and all will become clear.

[alstarz88]

I have removed the ims bearing cover and this is what i found

Nothing left of the bearing

my next question is with the ims bearing disintegrating like this is there likely to be dmage to other areas of the engine.

I bought this engine about 8 months ago off of ebay and can not contact the seller anymore account (withdrawn) but have some questions about the engine. it was listed as a boxster S 2002 engine but there is something odd about it like wiring differences which I had to change to get the engine to start. and the fact that it has a variocam setup i have not seen (if it is variocam) I looked for the engine serial number which seems to be blank. flat bit on one of the halves of the crank case.

here is a pic of where there variocam should be

[wvicary]

It is possible that the camshafts have jumped out of time. You need to verify the camshaft timing and if everything is ok contact LN Engineering as they have the most experts on this subject.

Actually that would be M96-24 serial 674 05525

Which would be 2004 Boxster S 3.2 liter engine 260 HP.

[alstarz88]

is that vario cam 2 then that might explain why it looks different

how does vario cam 2 work without the chain tensioning element

i have answered my own question with google. it is variocam plus does anyone have the wiring diagrams for a 2004 engine.

[Loren]

Yes, VarioCan Plus and DME 7.8.

You will need more than the wiring diagrams.

Check the other posts here for engine swaps. The differences are covered in those posts.

[RFM]

Maybe i misunderstood, but the cylinder heads on the pics are not VarioCam Plus.

[alstarz88]

ok looks I know what i need now does anyone have the wiring diagrams for a 2004 boxster

[Loren]

You can buy individual schematics on the Porsche website for $1.80 each.
