Good morning,
installed lpg some 3k miles ago, and played with the timing.
I've lost and ended up with either hgf (dont think so) or piston rings. Signs are oil mist blowing out of crank case breather, like 1l every 100mi.
Didn't do a compression test, but I know I've been driving with about 15-20 deg BTDC for about 100mi, and a lot with about 12-10 deg BTDC. No overheating tho (thank god I got meself a EGT gauge). No oil in the water either. Now I'm set on 6 deg BTDC.
Now three questions:
Checking if it's the rings is doing a compression test (warm, open throttle), then doing it again with a bit of oil in the cylinder, right?
Rebuild or put a 200tdi in?
I know I can get all parts for the 2.25. Are there any parts I can't get or can't do myself in a 200tdi?
Background:
S3 1978 (petrol 3 bearing, turner head 8:1 fitted about 12 years ago)
Doing lots of motorway miles (about 5k miles a year) with 50-60mph, but OD fitted.
