Engine problem 911 2.7 1976


Recommended Posts

Hi, I'm starting to rebuild a 1976 911 targa, 2.7 engine. The numbers are matching but that's about all that is still good about the car. But I love it and I know that is will take time and effort (and $$$) to bring it back to live.
I already did a few things before now starting the serious work: the engine. It is losing oil (they all do), but it is not running well at all. It makes a kind of 'clapping' noise. Difficult to describe so I posted a short video on youtube where you can crearly here that there is something seriously wrong. So I already know that I'll have to take the engine out of the car to have it rebuild, but does anybody can 'guess' what the problem is that causes this noise ? So I know a bit more in advance how bad it is...

It's hard to say - did the last owner run it without oil? did they let it over-heat? You just don't know without further inspection on a lift.

Why would you remove the engine? -- you need a visual inspection and compression tests. Both can be done without removing the engine.

Many head stud failures can be foxed without removing the engine.

noise sounds up top. maybe even front I.e. CHAIN TENSIONER ? Also sound exssive valve lash; scored camshaft / rocker due to oil spraybar clog ? Pay attenntion as you have start at the top front any way. Good luck, and don't fix what aint broke unless you know from experience or what you see is what you got. MJ.
