marc_p Posted May 24, 2011 Share Posted May 24, 2011 Ok, I have been stripping down the bay to replace numerous parts and also replace my valve stem seals. But I have a couple of concerns that I would like your views on: 1) When coming to remove the cam covers, the bolts that hold them down were finger tight on virtually all of them, I only needed a socket to remove 2 of them and they were only slightly tighter. 2) When I remover my coil packs, there was oil around the bottom of them. It maybe that I'm worrying about nothing but surely cam covers should be done up more than finger tight, which could possibly be causing the oil round the bottom of the coilpacks couldn't it? Any info appreciated Cheers Marc Quote Link to comment Share on other sites More sharing options...
Robzki Posted May 24, 2011 Share Posted May 24, 2011 (edited) I had exactly the same mate, I think its a common problem. All of mine were finger tight or less and had oil near the back of the engine and in plugs 5 and 6. I torqued them up, cleaned out the plugholes and has been fine ever since. was the source of a misfire, along with the coilpack clips. I'm not sure what the torque value is on them but sure its here somewhere. It won't be much though. Rob If you're changing the vss I would put a new gasket on anyway while you're there for peace of mind Edited May 24, 2011 by Robzki (see edit history) Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted May 24, 2011 Share Posted May 24, 2011 The rubber seals under the bolt heads perish and the bolts loosen off, they need nipping (I mean NIPPING) up regularly. The cam covers, if loose, will bleed oil into the plug valleys, and down the back of the engine. renew the bolt head seals when you do the stem seals. Use ONLY genuine Toyota seals, the Ebay stuff is NOT the same, or as good. Quote Link to comment Share on other sites More sharing options...
mellonman Posted May 24, 2011 Share Posted May 24, 2011 thats intresting to know as mine does this looks like i will tighten them up tonight does anyone the know the tourque setting Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted May 24, 2011 Share Posted May 24, 2011 5.4 N-m or 55 Kgf-cm, or 48 in-lbf You will need a small torque wrench, big ones won't go that low. Just nip up hand tight, if you overtighten you'll crack the cam cover casting. Quote Link to comment Share on other sites More sharing options...

Cheers guy's, really appreciate that , I got the proper VSS kit from MVP which also comes with new breather pipes and gaskets, I shall hunt down the part numbers for the bolt head seals aswell and get some from Mr T. Might explain a misfire/stutter I got whilst I was on the dragonba11, only happened twice over about 1000 miles but now I know why it may of happened.

Robzki Posted May 24, 2011 Share Posted May 24, 2011 If you don't have a torque wrench that goes that low, just tighten till they snap then back half a turn Thats a joke btw. As Mr Wilson said, they just need 'nipping' up. I'm sure with new rubbers they should hold fairly well anyway. Quote Link to comment Share on other sites More sharing options...
DaveR Posted May 24, 2011 Share Posted May 24, 2011 I had the same "oil in cylinder 6" problem a couple of years ago. New seals (only about £20-£25, if I remember right) and its been fine since. Quote Link to comment Share on other sites More sharing options...

mellonman Posted May 24, 2011 Share Posted May 24, 2011 just quick one to anyone that might know i just tightend these bolts up then went out for a spin and now making more boost i had to turn down the boost controler, when i say more boost i mean it was set at 1.3 but now making 1.4 so had to turn the avcr down by 4% on duty to make it back to 1.3, does that make sence? i can think oil preasure may be affected but boost strange but thats what happened.

Robzki Posted May 24, 2011 Share Posted May 24, 2011 The only way I can see this having an affect would be if you cleaned any oil from the plug recesses that were causing a misfire? Quote Link to comment Share on other sites More sharing options...
