Oil leak solved - Raceseng billet aluminum cam plate

[Superhatch]

I didn't have the gray RTV so I used the black/high oil resistance. Full cure says 24h. I waited a few hours and hoped it was enough. Still got some leaking tonight.

Noted, let it cure as per the RTV instructions!

Removed, reseated, re-RTVed, curing as we speak.

May 2013 build frs here with over 10 070 km and still no leak on original cam plate

Knock on wood


Also what causes the cam plate to leak?

[Astroboy]

does anybody know exactly where the oil passage way that the cam plate covers, go to? does it go down to the oil sump?

[MuseChaser]

Well, as I've written in a few other posts a week or two ago, I,too, have experienced the burning oil smell when the car sits at idle after a drive. The leak was too small to be noticeable, and the dealership missed it even though I asked them to look for it when they did an inspection for me last week, but, lo and behold, the leak was there, painfully obvious, today, just as you've all described.

Sooo.. the job is so small it ain't hardly worth humpin' to the dealership, other than to make them aware that this is an ongoing problem with the design. I probably won't bother. The question is...

Remove, clean it up, and black RTV it, or spend the bucks on the replacement part mentioned in this thread? I don't mind spending money for obvious improvement, but if a good reinstall works just as well, then I'd just as soon save the bucks.

Opinions?

Thanks..

While there have been posts of people successfully re-sealing the stock plate, there have been others that tried that only to have a leak occur again in the future. Resealing won't help the fact that the metals are of different consistency and heat up & contract at different rates.

The main advantage of the Raceseng part is the correct material, as well as the rubber o-ring. Combined with the gray gasket maker applied to small seam it seems to be a win-win.

Might be one of those situations like "do it right, do it once".

Side note: too bad all my images aren't showing up anymore in the first post. I don't think I still even have them or I would re-upload them. Sorry about that.

Is the leak the same if it's from here

Nope, that looks like it's your actual timing/valve cover which definitely seems worse/more severe. Someone correct me if I'm wrong

[Albaro08]

A friend of mine on mid Atlantic fb says timing chain cover

I have had both the cam plate and the timing cover sealed for this same issue

I have a feeling toyota is going to go with a big fuck no we aren't going to warranty your car

Mine was fixed under warranty. They fitted an improved plate design also

[Albaro08]

Did they make a tsb for it and also if they did can you tell what was the service they did becuase my dealer is lost in space with this one. So I'm wondering if toyota knows about it

Not sure if there is a TSB. They first changed the plate and reseal but I still had a leak. It was tracked to the cam cover. When my car was new it had a variable timing part replaced to fix the idle issues (ended up being an ECU fix). Seems they did a crap job of sealing it when the job was carried out

Ok ok so maybe toyota might have something on file for what's going on but no tsb but I know that they are going to fix this becuase I don't play to many bs games I'll just go through the right channels and get it done by them especially that I'm bare bone stalk
