well ive notice oil on the ground when i park my car the last few days, and its a decent amount.i figured i got an oil leak. i looked and sure enogh its coming from the back of my engine right where the plastic cover, that covers the pistons and such is(sry i dont know the name).
anyone know how much itl be to fix, and if i should go to the dealer?

 

You mean the valve over gasket is leaking? Change it yourself. Just need to remove the upper intake manifold to get to it.

 

wow thnx for the qick reply i had no idea there was a gasket there(maybee cause ima noob) any idea what could have caused it? or can they just randomly go? ill go pick one up later

 

Make sure all the cylinder head cover bolts are tight first. One might have come loose. Does it look like it's leaking from the bottom of the cylinder head cover? Picture is tough to tell.

 

lemmi go snap a better pic brb

 

Is it leaking from the seam i have pointed to in yellow?

 

think i should tighten that bolt? maybee i bumped somthing when changing my plugs

*wow my face looks like a potato in that pic*

 

Yeah from the area he's pointing to, it looks like it's either one of the bolt holes or maybe a crack in the cylinder head cover. Looks too high to be the seal.

 

wow, really can't tell from those pictures. Do any of the bolts seem loose?

 

not really, ill tighten the bolt a bit and see what happens

 

You still didn't tell us where the oil looks like it's coming from. See Kris' post #6 above.

 

Cant really tell from that picture where its leaking. Try tightening that bolt up some to see if its loose. Also take a rag with some degreaser on it and clean that area to keep a eye on it and see better where its coming from

 

Could be one of those valve cover grommets. Maybe even a spark plug tube seal?

 

Ya know what, that's probably what it is.

 

ok now im gonna have to ask.... whats a spark plug tube seal cause i just looked and took mor epics and i cant find the source

 

it does seem to be coming from around the coils..

oh and as per fsttyms post it doesnt seem to be around the egdes, i asume thats where the gasket it

 

you have to remove the valve cover in order to change the tube seals. I don't think it's very hard to change them once the cover is off. You can either buy the tube seals separately, or in a valve cover gasket set (ask to make sure it comes with the tube seals). Oh, and some brands sell a set for just one side. BTW, I've never done this before...

 

can you describe where the tube seal is located? also acura oem parts says price is 150$ for the gasket set, is that right

 

once the valve cover is removed, flip it over and the tube seals should be sitting right there. you'll notice the three tubes coming up out of the head (where the spark plugs are). Again, I haven't done this on my TL, but from experience with other Honda's...

You can check aftermarket parts stores for the gasket if you want. You should be able to pick a complete valve cover gasket set up for about $40-50.

 

thx

 

They are part 5. (3 each side) they go where each plug hole is to keep oil from leaking out

 

I replaced mine when I powdercoated my cylinder head covers. I seem to remember they were a bitch to remove and put back on.

 

I'm getting NGK Iridium IX this weekend. Was wondering if you think I should replace the spark plug seals at the same time? Got 100K on 99TL

Thanks
Itch

 

I'd only replace them if they were leaking.

 

Only if leaking.

 

Thanks guys!
