So I did compression tests on my RRC today. #1 90 PSI and #2-8 run 112PSI to 125PSI.
The engine is weak and when it idles (now that I have the exhaust fixed) I can hear a air leak sound on the driver’s side of the engine at idle. I’m wondering if the front of the #1 cylinder head gasket is leaking.
Everything I’m seeing from other people’s posts on the net say 170-200PSI on a test. Looks like I’m low all around. The odo shows 250k+ miles. I imagine I’ve got a tired oil pump, oval cylinders, worn rings, tired valves, and a bad head gasket at this point. 🙂
Thoughts? I’m thinking I’m looking at a full rebuild.
I’m certainly no expert – but replying anyway – trying to make this forum more of a thing…
Sounds like head gaskets to me – have you ever taken it to JC British? I took the Disco there last week, not cheap, but I got a pretty good feeling about the place and the people – and a bit less expensive than the dealer. They also seem to have genuine interest in working on older trucks, vs feeling like they’d rather be doing oil changes on Evoques….
