Hi guys,

This forum has been great for a newbie like myself getting into Skylines and beginning to get hands on, however I'm out of my depth on this one. Can someone please take a look at the video below and help me diagnose the noise?

Car has had a slight oil leak on the rocker gasket cover, due to be replaced this weekend. Timing belt was done less than 4 months ago.

Thoughts? Any help is appreciated.

A bad exhaust leak from downpipe gasket or exhaust manifold etc

or broken ring lands? Try a compression test.

Or use a long screwdriver or similar and stick one end in your ear and the other on the block, head, cambelt cover etc to try to locate the source of the sound.

I wouldn't use a helicoil there........go time sert every time!!!!

The trouble is if you get a slight soot/carbon buildup on the spark plug thread when you take it out [regular service etc] it can grab the helicoil and bring it out as well. I've never had an issue with time serts.

      Nice. Dont worry about the time of not running. My current skyline hasn't run since I bought it. About 8 years ago.

      It's also worth noting that I am heavily and unconditionally biased. I've had a lot of cars including some GTRs a fair while ago. I love my BMW's now a lot. They make no sense a lot of the time and the guys on here remind me regularly that I could get something else that does what I want better and cheaper. If you're going to take on an older BMW it's definitely a commitment. If you bail on it early you'll lose money and also the ability for it to put a smile on your face. Stick with it and it just gets better.  f**k I should get into advertising.

      Careful with posts like that around here without the flame suit on @cobo_11! 😂😂 My 330i journal is on here too. That car was so good and super reliable. We still have a 130i in the family which is almost identical to the 330i and easier to find in manual. It has also been almost faultless over the 6 or so years in the family.  I used to want an M car a lot more than I do now but if I'm honest and without trying to sound like a wanker, I can get such good performance and handling out of my 335 without needing to worry about all the crap that goes along with M car ownership. I don't need to worry about my bearings or subframe issues or the cost of replacing brakes or suspension or whether it has been impeccably maintained. And I can leave it places and not get upset when it's always filthy.

      Great write ups / details / photos. I'm sort of on the road to E90 ownership (325i or 330i), haven't hit the fork in the road yet "Yes" | "No", and some of the issues you've faced have me nervous for the age these are getting to nowadays (that wiring, jesus), but I'm guessing the pro's of ownership are still outweighing the con's? Of course, if the bloody tattslotto ROI actually went my way...E90 M3. And I'd have the cash to do all the extra lovely maintenance THOSE require. 😄
