mightymetros Posted November 30, 2004 Share Posted November 30, 2004 Got the head back on the car, been running fine apart from the 4 stripped threads in the head where the cam cover bolts too *mad* . Got some longer bolts and torqued them up, which stopped the slight leak there, but, the car is throwing oil everywhere on the passenger side of the car (its in a metro so the gearbox side). It is ok with road driving, but as soon as i go on track and go round corners the engine just losses lots and lots of oil (nearly 1/4 on a couple of laps) Any ideas where it could be coming from, and why it only comes out on corners? Its a 1800 vvc engine. Oil is even on the underside of the bonnet thank you sacha Link to comment Share on other sites More sharing options...
Sheds Moderator Posted November 30, 2004 Share Posted November 30, 2004 Blocked breathers causing crankcase overpressure? Worn rings causing above? U/S gasket? Dead oil seal somewhere? Overfilled sump (wrong dipstick...)Clean the engine with a paraffin gun or steam cleaner, then run it at speed and see where it's leaking. Link to comment Share on other sites More sharing options...
mightymetros Posted November 30, 2004 Author Share Posted November 30, 2004 Cleaned the engine, but no matter how hard i rev it stationary i cant see a drip from anywhere. sacha Link to comment Share on other sites More sharing options...
Myles Posted November 30, 2004 Share Posted November 30, 2004 It'll have to be a trip around you local Tescos tonight then. Can't see how else you are going to reproduce it if it doesn't normally happen in road-use either.... Project Scope-Creep is underway...

Normans_Ghost Posted November 30, 2004 Share Posted November 30, 2004 It sound to me like it's spilling out the cam cover when the oil is being thrown against one side or other on cornering.

mightymetros Posted November 30, 2004 Author Share Posted November 30, 2004 Myles, thanks for the advice, although it is rather ironic that our local tesco, and local police station share the same car park *tongue* 😬 😬 😬 😬 🙆🏻 🙆🏻 🙆🏻 Norman, thanks, ill get a new gasket tommorow, and re-tap the holes to M8 if possible and give it a whirl. I have been told that that side of the engine can suffer from oil starvation and thus why it doesn't come out in normal driving conditions Link to comment Share on other sites More sharing options...
neil.cavanagh Posted November 30, 2004 Share Posted November 30, 2004 presumable the engine is transversely mounted as its a Metro? So the oil will (presumably) be coming out of one END of other of the engine, rather than the sides (assuming 'sides' are the long edges that run north south in a proper car but east/west in a FWD tintop). Nothing stupid like the oil cap or dip stick not seated properly? Link to comment Share on other sites More sharing options...
mav Posted November 30, 2004 Share Posted November 30, 2004 No, we checked that Neil. Difficult to tell where it was coming from, but I suspect that breather Sacha... Link to comment Share on other sites More sharing options...
neil.cavanagh Posted November 30, 2004 Share Posted November 30, 2004 mav, if it was my car I'd be looking very very closely at the apollo tank about now.. .but we know that is a whole story in it's self!! 😬 😬 Link to comment Share on other sites More sharing options...
tiddy1 Posted November 30, 2004 Share Posted November 30, 2004 Is the passenger side the flywheel side? if so coild it be the crank oil seal and then oil being thrown about by the flywheel?, seal may only be leaking due to oil sloshing against it on cornering. also VVC engines seem prone to iol retention in the head at high revs, may be talk to DVA simon Link to comment Share on other sites More sharing options...

mightymetros Posted November 30, 2004 Author Share Posted November 30, 2004 I do have one of the breathers going to atmosphere, but there is such a vast amount of oil there. But, as simon stated, if the vvc retains oil in the head at high revs, it could be possible...................mmmm, the flywheel/gearbox has covers over, so it is unlikely that the oil would be sprayed everywhere isnt it??? sorry guys, im just stumped. I may try and knock up a temporary catch can to see if it is the breather. sacha If it was the breather, why doesnt the breather from the second exit on the head, that goes to the vvc manifold, put oil into the manifold and cloud everything with blue smoke as it burns off through the engine Link to comment Share on other sites More sharing options...

sjmmarsh Posted November 30, 2004 Share Posted November 30, 2004 It sounds a bit like my 7 - one of the bolts has stripped on the cam cover (passenger side, nearest the footwell) and it leaks like a stuck pig on a track (runs forward along the side of the engine, presumably under braking, and then down the side of the engine and across to the bay via the engine strut). Sometimes oil gets on the manifold - very disconcerting when you come out of a bend and see a big blue white cloud in your mirrors! I think it just means you have a camcover leak somewhere - follow Norm's advice and clean it up, take it for a quick thrash and see where the oil is. I am off to the garage on Friday to get the stripped thread retapped. Steve Link to comment Share on other sites More sharing options...
Johnty Lyons Posted November 30, 2004 Share Posted November 30, 2004 Cam ladder to head sealant not done properly especially at corners oil retained in head on fast cornering being forced out and fan firing it everywhere . Dosn't happen on tickover or when your not throwing car about. I find lots of folk havn't a baldy about how to seal the cam ladder /head interface So I'd look there first. jj N.I. L7C AO.

Dave McCulloch Posted December 1, 2004 Share Posted December 1, 2004 Johnty O/T, but as I'm shortly going to be putting a head back together, are there any tips or gotchas in sealing the cam ladder to the head? Thanks Dave Link to comment Share on other sites More sharing options...
prs Posted December 1, 2004 Share Posted December 1, 2004 Rather than retap the threads it would be better to Helicoil, this will provide a stronger thread and will not be prone to stripping in the future. Phil S7SVN Link to comment Share on other sites More sharing options...
John Howe Posted December 1, 2004 Share Posted December 1, 2004 Dave, make sure you clean the surfaces and use the correct Rover goo or equivalent. Do feel free to bring it over to the farm if you want a hand... tel 01444 892127) JH Deliveries by Saffron, the yellow 222bhp Sausage delivery machine Link to comment Share on other sites More sharing options...
Johnty Lyons Posted December 1, 2004 Share Posted December 1, 2004 John summs it up........ absolute cleanliness and make sure both surfaces are completly flat then carefully apply Rover Glup not to much it'll fill the oil ways and use new cam oil seals, tighten up in correct order a little at a time so as not to distort the assembly. None of mine [touches wodden object on top of shoulders] have leaked yet but i've seen a fair few that have. jj N.I. L7C AO. Membership No.3927. Se7en Services.N.I. Caterham Service Agents.
