G'day lads,
I'll cut to the chase, I bought a really cheap R32 with an RB20 that is only running on 5 cylinders. I have done a compression test and all cylinders are around 127-130 psi, which I think is pretty good? Except for cylinder #3. It has 0 psi compression. And yes I mean 0
I was wondering how I can determine whether it is top or bottom end problem? I am going to embark on taking the head off as I have a feeling that a valve is not closing correctly on that cylinder, if this is the case it should be a fairly easy job. But if I was to rip the head off with the engine still in the car, than it could get a bit messy.
Is there a quick way of trying to work out whether the piston is cracked/rings gone without removing any parts? I have tried the squirting oil into the cylinder and doing the compression to no avail. As it has no compression anyway.
Cheers
