Default Compression test. 2110cc
Ok I have a fairly new 2110cc motor running/044 heads dual valve springs patter 1:4 rockers fk87 cam
I have just done compression test on all plugs out throttle fully open,
The reason is it seems to be burning a bit of oil, it ticks over lovely and sounds rea lily sweet
Cylinder 1. 120psi
2. 120psi
3. 120psi
4. 140 psi
Is this just a case of the. Rings have not bedded in properly yet,or could. It be something else.
The engine isn't in the car yet just on a test bed
Any advice much appreciated

Re: Compression test 2110cc
What was your target compression ratio?The 20 lb difference can be to unfinished ring seating.

Re: Compression test 2110cc
Its probably better to do the compression test again after the engine has a few hundred miles on it.
Hopefully the 120psi cylinders will come up close to the 140psi cylinder. With stock or near stock compression ratio you are looking for 130+ psi on all cylinders with a fresh engine.
