_Rob_ Posted February 2, 2007 Share Posted February 2, 2007 Im in the process of changing my timing belt. I noticed a light film of oil behind timing belt cover no. 2 once id taken it off. this film was only below the head / block join. Upon wiping this oily film off the block, i noticed the oil near the corners of the head was gold, almost fresh, when compared to the rest, which was a mucky grimey kind of oil. I looked to the sides of the block and had a feel, again in the corners near to the front, and i had gold oil on my fingers again. Now this is only a little bit of oil, nothing massive. However, im worried as the only place it could be coming out of is the HG, isnt it? When the car runs, there is no problems, no white smoke, just a little condensation on cold mornings. I had a tad of blue on start up, however after i removed that CATs, this dissapeared. My main question is...can i put it back together and hope for the best? Could the head bolts have become loose over time? maybe try torquing them up a bit? Any advice appriciated! Quote Link to comment Share on other sites More sharing options...
Ian C Posted February 2, 2007 Share Posted February 2, 2007 It may be coming from the cam shaft seals, and only transferring onto the block off the cover plate after it's got past the head? If the head is leaking oil I imagine you'd have much worse issues as well... -Ian Quote Link to comment Share on other sites More sharing options...
_Rob_ Posted February 2, 2007 Author Share Posted February 2, 2007 Thanks for the reply. By cover plate, do you mean the metal plate behind the cam gears? Quote Link to comment Share on other sites More sharing options...
mikeyb10supra Posted February 2, 2007 Share Posted February 2, 2007 It may be coming from the cam shaft seals, gaskets from toyota are not expensive, not a major problem, Quote Link to comment Share on other sites More sharing options...
_Rob_ Posted February 2, 2007 Author Share Posted February 2, 2007 Im guessing thats a cam out job? Quote Link to comment Share on other sites More sharing options...
mikeyb10supra Posted February 2, 2007 Share Posted February 2, 2007 if its the cam cover gaskets then no....cam doesn't need to be taken out Quote Link to comment Share on other sites More sharing options...
_Rob_ Posted February 2, 2007 Author Share Posted February 2, 2007 cam cover gaskets? thought it was cam shaft seals? ive got the cam covers off at the mo cos the gaskets were leaking slightly at the back. But this leak is at the front, and way lower down that the cam covers. And there doesnt seem to be an oil trail from the cam covers. Quote Link to comment Share on other sites More sharing options...

Ian C Posted February 2, 2007 Share Posted February 2, 2007 No, they don't need to come out - you can wheedle the old ones out and poke in new ones without removing the cams. -Ian Quote Link to comment Share on other sites More sharing options...

_Rob_ Posted February 3, 2007 Author Share Posted February 3, 2007 Thanks guys. Ive had a closer look today, around the cam seal area and around the metal backing plate and there does seem to be oil coming from there. Quote Link to comment Share on other sites More sharing options...
Mike_Mac Posted February 3, 2007 Share Posted February 3, 2007 Could the head bolts have become loose over time? maybe try torquing them up a bit? Hi mate. Don't try re-torquing, as they're stretch bolts. Once they're set any further torquing can put them under strain. Quote Link to comment Share on other sites More sharing options...
