Need an engine shop in Los Angeles for N63 S63 valve work

[BlackBear]

I think a valve might might not be working correctly.

ISTA is no help. I got misfire codes across bank 2, Cyl. 5 show very low compression. Car goes into limp mode. ISTA does a guided rough running test that starts with bank 1. That bank is OK. When the test goes to bank 2 ISTA stops the test because bank 2 runs too rough.

I have not done a leak down test yet. Waiting for the tester.

I need a shop that has ample experience doing valve seals, taking N/S63 valve cover gaskets off, etc.

Thank you.

I did some more investigating yesterday.

It turns out Cyl. 5 has one intake valve that does not open at all. I put a camera in the cylinder and turned the crank.

I think the hydraulic valve lifter is faulty. If the spring was broken the valve would always be open.

Do you guys agree with my analysis?

I don't have the tools for this job, you need the AGA valve/timing tools to get the cam shaft out and remove the valve springs.

Who can do this work in Los Angeles?
