Prayers lifted. I just did this job about a month ago. Did the timing belt service and found the oil seepage about 50 miles afterwards. Had to take it back apart. Main seal was squished. Looks to be you have the same issue. Clean it out as well as you can. Also everywhere that main seal touches should be surgical quality clean. Have fun with it... as I was once told on the golf course “it’s like a carousel. You pay the quarter. You get on. The horse goes up and down and around. Circular.” No idea what that means but it seems to fit every time I crawl under my truck.
Thanks, that’s really what I’m trying to avoid. Did it fix the leak when you replaced the front crankshaft main seal?
 
Installing the mouldings over the rivets did nothing to lower the wind noise I'm chasing down. Oh well, at least I'm slowly returning the truck to completely OEM
Did you pull out all threaded fasteners and use plastic-capped rivets?
 
Yes, there were only two non-OEM fasteners. Due to my slow uptake on certain things, I bought 20 rivets from Toyota .... just in case.

Plus, the passenger side has had OEM rivets forever, and that is the side where my wind noise originates.
 
Finally had the opportunity to remove the timing belt, harmonic balancer, crankshaft gear and verify where the oil was seeping: the front crankshaft main seal? Anyone can confirm this maybe?

Now got to swing by later for some purple power degreaser to get this sludge cleaned and detailed before replacing that seal.
When I did my timing belt, I had the same looking crank seal. It isn't the crank seal. I replaced with brand new OEM and it isn;t from there. It would look a lot greasier and messy by the drain hole cover. Crank seals don't usually leak like that til 300-400k miles. I thought like you did, and replaced the seal, but it still looks like that after 10k miles with the new seal.

My bet is that your dipstick tube is leaking. Makes it way around the drain hole to make it appear its coming from the crank seal. You would have a ton more buildup around the seal if it was the crankseal leaking.

Interesting. I just checked it now and yes there is a build up of gunk and sludge in the base of dipstick too. Thanks for this info @hickuptruck. Will a new dipstick tube fix it or is there a gasket for it?

That's from THIS golf course! :D

Appreciate it. Any tips on how to remove the dipstick tube?
Clean area around the leak, because it would get sucked up by the oil pump. Then its one bolt holding the tube in, then pull the tube up.

I'd break out a roll of your finest duck tape and start masking all the cracks, seals and transition surfaces. Do it one by one and you are bound to find the culprit.
 
You know, I tried that already and never found the source of the noise. I used painters tape over the pillar, windshield to metal, over the top of the windshield to paint, on the bottom windshield to cowl covers. I've even shoved paper towels in the crevices I could see where the hood hinge meets the body and surrounding area. No change at all. I also went as far as to caulk the windshield on the INSIDE where the door handle trim is from top to bottom.

Perhaps I'm just expecting too much from a 20 y/o rig with a replacement windshield.

Perhaps this is better suited for its own thread, but can you post any pics of the top side rubber strip? Mine looks like this:

That was a pita but got it out, thanks again to you and 2001LC, new part is on it’s way.

I have the front skid and was close to ordering the rest, but at around $800 shipped for the full set, I’ve been wondering if I should just order the dissent set for only $400 more.

If the $400 isn't a big concern for you, then I'd say yes. The thought crossed my mind once or twice yesterday to sell these and do the same.

Started cleaning the AC evap coil which is caked on with junk. Trying to suck up as much as possible before I do any sort of spray down so it doesn't clog the drain. Looks like some of the fins are broken off :doh:

Replaced all the ignition coils since they were cracked. Planning to keep the old ones as spares since they still functioned.

Found a dead battery after a night of rain with some really slight dampness in parts of the cabin. Not sure if it is related or if I just drained the battery since I have had doors open for the past few weeks without the engine on while I do other stuff. Investigating sunroof drains, windshield gaskets, and roof rack bolts to see if any smoking guns.

Also borrowed a better borescope from work to take a look at the time-sert that is broken in my #8 cylinder and the piston head (videos of damage below). Welcome to any comments good, bad and ugly about this. I'm just hoping its fixable since I feel pretty bummed about finding it when I haven't even really had a chance to do much besides starting my baselining.
Thread Side View (Piston to Spark Plug Tube)
Piston Head

Finally, found a bushing that is trashed so going to do a review of all of them to see what needs to get replaced.
