Listen to kronus. it's probably a bent valve. you're gonna drive yourself nuts and replace the valve anyway in the end.

if your valves are bent, planing the head won't do shit. do some diagnostics first to figure out if it's top or bottom end.

Yea i plan on checking all that when head is out. Im gonna pull head inspect the valves and what not and make sure its true and not warped. If its good to go I'm just gonna run it. If not i will rebuild but not for a while so car would effectively be dead. What you mean figure out if its top or bottom end? Id think the head gasket is my problem.

I pulled valve cover and nothing looked out of place. So until i pull head i wont know anything else. Im down to the point where no matter what the head needs to come off to find the issue.

icky.

I have a couple spare B34 heads if you need one.

I got a euro spec b34 head in my basement that i will rebuild. For now im doing bare minimum gonna pull head lay a straight edge on it. If its in spec i'll buff block and head put new gasket on and run it. Its half ass and not the right way to do it. But i need this bitch on the road and can fix it properly over the winter.

Ouch. Man, your m30 hates you. Mine doesn't seem to give me problems.

Yep my buddies 911 only ever sees cold starts every month or so just to run the engine. Granted it runs pretty rich on cold starts and backfires tons, but the plugs are very black despite the car running really well when it's warmed up.

Welp.....

Thats what im hoping is the reason they are black cause its only gotten to op temp 2 times. I will take my fuel pressure tester out to the shop and check it. Really hope i don't have to rebuild the head or motor.

Well I hope the compression test shows good numbers :P
Maybe check fuel pressure too if you haven't already.
Plugs could be black if the engine has seen a lot of cold starts but not much running at operating temp

I would think mine would be fine since they are brand new. Its is rich.

Thats cyl 1 spark plug and they all looked like that.

Sorry correction fpr or injectors usually cause rich.

Mine had good spark, testing it with the plug out and multimeter didn't show it. The plug wire was intermittent. Heat or vibration caused an intermittent misfire at any rpm. I got a nice looking set at the junkyard and swapped out the cables.
I'm not a wizard when it comes to the m30 but I read a lot of posts about misfires caused by plug wires. They are tough to fix because most people won't shell out the cash for a set of plug wires on a hunch.

I'm betting it's a vacuum leak though. So many places that could leak, even the oil cap.

I pulled my spark plugs and let the injectors spray fuel into cylinders from what i could tell i had fuel in all cylinders. The injectors were refurbished so they should be alright but could be stuck i will tap them with a wrench and see what happens. My battery died on me cause i left key on so its sitting on charger right now.




Ive checked all spark plugs and they were all getting spark and they are new plug wires. Gonna do a compression test once battery is charged up.

that's not running right. a valve adjustment is not going to fix that. are all your injectors spraying?

High idle is lean. Worst problem to have. Fpr or injectors usually cause lean. Check fuel pump, all vacuum lines(yes all of them), throttle gasket, intake gasket, oil cap, PCV hose. Basically everything

My m30 also ran terrible, ended up being a spark plug wire that was bad.
