Hi all,
After trying to get to the bottom of a lumpy idle, I decided to buy a tester and do a compression test on all cylinders.
The car was warm when I tested it and the results were consistently low, with cylinders 4, 2 and 1 reading between 110-120 PSI. Cylinder 3 reading was about 130 PSI.
The spark plugs from cylinders 4 and 2 had oil on the threads. No noticeable signs of oil contamination in the tips of the plugs (any of them).
This might not be the cause of my lumpy idle, but it’s certainly less than ideal…
There’s probably a few things that could cause that, but the only thing I’d be able to check and fix myself is the timing belt, if the low compression is caused by bad timing. This is unlikely as the belt is only 2 years old and the csr ran fine after changing it.
What’s the going rate for a decent 197 engine?
Alternatively, what’s the rough cost of a megane engine swap? Assuming I remove and install the engine myself?
