It'* only a little bit... and funny you say that..

That'* the reason the upper intakes fail on the series two'* with the composite (aka plastic) uppers.

Cool...... Well i am glad that I have the aluminum EGR'less bonnie then. Woot woot!

I also seem to have an oil leak, is that a common thing? I guess my BRO'* mechanic said it was the oil pan and replaced the seal and the pan, but still leaks, part of the oil pan and the trans pan along with surrounding areas are wet. I hate leaks.....

Our 3800'* are notorious for running forever. They are also known for front main and rear main seals wearing and seeping. (Crank shaft seals).

The only way to fix either is to spend too much time with wrenches in your hands.

The other thing that might do it is, when Highlander was replacing a motor....we had to get an oil pan gasket from the dealer. Automatically the parts guy grabbed a tube of "GM engine sealant" and said it was required when doing the gasket. Typically gaskets are put on dry w/o goop...this one should be done with goop according to the dealer.

Yes..my rear main seal is seeping on my car and it'* annoying. I find that if I wipe the pan each time I change the oil, it stays pretty clean and dry.

Well maybe I will try and get a new pan gasket with the goop so to speak, and yes a 2 hour wipe down after the oil change made it look allot better. Lets hope it stays that way.....

2 second...lol if you are spending hours on this leak...change that gasket..lol

Good ideer......

Or clean it and figure out if it'* the pan or the main seals.

Mine seems around rear seal to but, not whole lot. I am running mobil 1 in the car it did make it run smoother

Thanks for the tip! I was wondering if I could run synthetic in it, since it leaks ya know. I run amsoil in everything I own, but might not be good for this old girl.....

I have valvoline max life in mine at the moment. I think its syn blend, with the larger filter as I have read about here.
