interesting issues..

[akc]

hey my subie just started doing some different things..

1986 subaru gl 4wd. hatachi carb.. first off the timimg belts went we fixed them and also fixed the oil pump.. after doing this we found that one of the vaccum? lines on the carb was broke.. we plugged that and it seemed to run fine.. (ment to get a picture of it to make sure it was not important but...) We also fixed the exhasut manifold gasket at the same time.. ( the vaccumline is a small one on the drivers side that goes straight up. very small)

 

now the Tach.. jumps around when you are running the car... not too much maybe just 3-4 lines enough to make you wonder second the car starting leaking and burning oil .. when it has to work hard it is letting out some blue smoke...car sounds OK... questions? what do you think is happening? rings??? do you think it could be caused by the line on the carb?? Or do you think it was coincidence. Anything we can do or is it on its way out..

 

Thanks.

 

would get you some pictures but I lost my camera.

Burning oil could just be the breather lines - check the breather lines and the PCV valve and it's small filter element in the air filter box. If it's not that then it's probably valve stem seals - nothing to worry about really - just annoying.

 

Jumping tach could be an alternator on it's way out, or could be play in the distributor shaft. Both can cause tach jumping to varying degree's depending on how bad they are.

Tach could also be a loose tensioner on your timing belt DAMHIK
