Dumb Question Thread - No Flaming Allowed

I was tightening the cylinder head bolts and one of them, number 12 in the diagram, was just a little easier on the resistance side than the rest of them. I was still able to get the 30nm+90+90 degrees, I used a snapon techangle, but it just was smooth unlike the rest had which had more of a tight/clamping feel. I cleaned the bolt holes and used compressed air beforehand but now I'm rethinking if somehow maybe there was residual brake clean or I lubed up the threads with too much oil (used an oil can and just went down the threads, not much imo). It could just be OCD. Any experiences with this/insight?

Ah interesting, I was wondering why even with the fender pull the lip wasnt flat and still so thick. Thanks, yeah that sounds like a better solution, ill try that instead of cutting, less chance of accidentally cutting a spot weld too lol.

EDIT- following up, after taking another look at the inner lip, the shop that pulled the fenders pinched the top of the lip ‘channel’ closed, so wont be able to get a wire wheel in there to clear out the rubber :/

The inner and outer arch meet there as kind of an U shape which not your typical L shape that you can easily roll, the U shape is very strong.

There are spot welds are on the inboard side of the U shape, if you cut off the entire channel, your inner and outer arch will no longer be connected to eachother, you can solve that by welding the entire perimeter, which is what I have on my personal car, but obviously it will need painting on the outer arches at that point, you also need to be careful of heat control and warpage.

Another approach without welding is to first cut the U shape into the L shape, by removing the inner edge with the spot welds, and then carefully only cut out the inner arch part of the L shape, not the outer arch part, then apply panel bond adhesive and fold the outer arch over the now cut inner arch, and seam seal it afterwards, that is how a CSL is from factory.



Here is a CSL for reference.

Hmm, mine were new. Maybe they're not as thick as originals?

Anyone remember how many selector rod washers were needed when installing their AS SSK?

I was surprised to need 2 per side, double OE, to make it snug?

Yes I did that with old ones.

Theres rubber in that channel, I would remove that first with a wire wheel. Then you can roll the inner fender flat to the outer fender.

Thinking to cut off the inner metal lip on my rear fenders for better tire clearance/prevent rubbing with wider wheels and tires. Theyre currently pulled but the lip was just rolled rather than being shaved. Whats the best way that folks go about this? I was thinking to just tackle this with a dremel using a metal cutoff wheel after marking the area with a line.

Does anyone have a PN or a suitable replacement for these caps on the ITBs?

Appreciate the explanation. Are you saying that a Blackstone test can wait until 100,000 miles? The car is currently in the low 9X,XXX. Is the $2.5K service range for each of the Big 3 repairs?

I just bought a car with 144k I’m gonna do all the fluids just so I know their mileage. Oil should be changed every 5k so it it was done at 90K and 95K should be fine. Till the next 5K interval.

rod bearings should be the cheapest, but there’s a lot of should refresh items while your doing that service that can make it add up to 2.5K

Vanos depending on exhaust hub can be between 1.5-2.5K again few extra things you’ll want to replace while you’re in there.

I would offer him 5-7.5k less than asking if you feel the big three are that important. IMO, Vanos is the only must as rod bearings should be serviced via blackstone report of wear that indicates it, but you can always just go with @100k. Subframe reinforcement as long as it was street driven and not tracked shouldn’t be an issue.

everyone has various experiences, weigh the pros and cons and what risk you’re willing to accept. Each service with labor and parts is roughly 2.5K + or -

I’m currently eyeing an ‘04 E46 with 9X,XXX miles that looks be in great condition with respect to the interior and exterior. It’s currently for sale with a reputable dealer who providedthe Carfax which shows regular service throughout its life however no mention of any of the “Big 3” repairs. The sales guy would only say that he doesn’t know of any major issues before pulling out the dealer speak that “it’s one of the cleanest specs he’s seen.” As a novice to the E46 platform and used car purchases in general, my question is whether there’s a way to verify if the Big 3 have been done and if the dealer response is a potential red flag. Thanks in advance!

You can put it on a rack to check if subframe reinforcements are present, easy to spot. You might persuade a BMW dealer to get you the service history based on VIN which then might tell you if the rod bearings were ever done. However, that obviously isn't foolproof as an independent could have performed the service. Bottom line, no way to check rod bearings or vanos unless you get lucky with a dealer service report.

Maybe it depends on how deep as you don't want to diminish the lift and/or duration. What's been done before is weld on more material, then grind it down back to original shape.

At most there's maybe a mm missing from c6 lobe. Not sure how to accurately measure and portray this as the material eroded is over the circumference of the lobe where it applies contact to th rocker.
