Hello All,

I am new to this forum and I would like input from the Z community on a good machine shop.

Background:
I have been tracking my 2006 350Z for around a year, and I have low compression (150psi) on at least two cylinders and 25% leak on at least one.
How I noticed that I had a problem was oil was gushing, yes gushing, from my oil catch can the last time I went to Buttonwillow, so I know if have excess pressure in my oil system.
I am going to be tearing off my intake manifold and valve covers to isolate the leak to either the rings or the valve/seals (air was leaking from oil fill cap).
Open to other ideas on how to trace the cause of the pressure leak.

For either the rings or the valves, I am going to have to do some engine work and I would like to get the communities recommendations on good machine shops that provide quality machining and preferably, are familiar with VQ's.
I prefer NorCal but will drive to SoCal if needed.

Your help is greatly appreciated and I thank you ahead of time.

 

Go to the machine shop that has a torque plate for honing/boring the block! I'm sure there's shops in the Sac area that know what they're doing, just gotta ask. I built my engine, cost wise it wasn't much less than just ordering a built short block from a vendor like IPP.
