I believe the older records have probably been discarded. I dont believe SC has any records over 30 years

A little story... I had a 95 suburban that went in for an oil change. Well they forgot to refill the oil but I really couldn't prove it. It had a rod nock after that. A local racer told me to run 20w-50 in it. Quiet as a mouse. We ran it that way for a long time

I didn't see a source for one in the states

Shawn, Let's slow down a little bit... You have one of the best people on the forum to walk you through this and he can teach you the electrical but you have to do your part. People on the forum are trying to help you repair your car from hundreds or thousands of miles away. When we ask questions you need to answer each one in order. You also need to read the FSM's some. You won't understand it all but it will make it easier to help you fix things the more familiar you are with the manual. If you can do those things the people on the forum will help you figure it out. Ive seen it happen 100's of time. Steve is giving great advise and there is no reason for any of else to give advice and confuse the issue. Just be patient

May never know. Maybe it got serviced at some point and the recessed plug got destroyed? Maybe the factory used the wrong plug pr ran out of innies...

where will the next gen system get fresh cabin air?

Nissan still sells most of the rubber bushings with a few exceptions that are NLA

Yes, I agree. Deal with a smaller rebuilder. Ask for your original back, no exchange

If you show oil pressure. .. I would experiment with heavier oil 15w40 or 20w50 If the sound gets better it's a bearing issue. If it goes away, run the heavier oil until it breaks or you're ready for a rebuild

If the booster's bad, what is the problem with sending it in to be rebuilt?

Has oil pressure been confirmed at the block? What oil is in the engine? Is there sufficient oil in the engine?

I'll try to remember to do that when it get's here

Ahh, Z4 M roadster. The ever sexy S54 engine! I bought a 3.0Si today

I was asking the next Obvious question, sort of for posterity's sake

What are the ramifications of not having those components?

Holes have to be welded closed. That requires paint. I suspect there is a source for new rubber but don't know where

They are riveted on. there will be 4 or 5 rivets in each piece under the rubber

Yes, do save the tip. They are NLA

I think that's not recoverable

You could always take the door to the paint shop. Have them scan it and see which formulation the scan is closer to

I would go with Bumper Automobile I believe

Slow poke! Its 5 o'clock somewhere! 😉

Been there; done that! 😞

Cerium oxide is the traditional method but I routinely polish glass for Cody's car with paint cutting and polishing compounds. Works good, but wont remove the really deep scratches

Why did you need to switch tanks for the LS swap? Thats an EFI tank. Are the lines not large enough?
