Well I changed the oil cooler about 2 months ago as i was getting oil in the water and the car has been off the road more than on since if i'm totally honest.
So every now and again i check the oil contenet in the coolant bottle and sometimes there is nothing just a couple of floatie bits of oil then another day there is a comp film of oil on the surface.
I have done a compression check and got 200psi per cyl done a head gasket check all ok, When I done the oil cooler I did flush the system then a couple of weeks later I got a split hose so it basically got another coolant change so could this oil just be what is still laying in the cooling system or is it going to be head gasket????
Any ideas people?

Oil gallery leaking into water jacket! you might have perfect compression! but I think your headgasket has gone!

Yeah water and oil channels can go in the head gasket and the piston rings in the headgasket not "piston rings" can be absolutley fine so compression wouldn't be down. Change your headgasket otherwise you'll end up with all sorts of problems would be my advice having just done one :)

Would you still recomend getting the head skimmed as its not gone from water way to compression etc?
Spose just to be on the safe side of things get it done???

Can't skim a 16v head I'm afraid matey pistons are too close to the valves. just do the gasket and hope for the best :)

Could well have a crack in the water/oil pathways which would explain the oil getting into the water, obviously this is worse case scenario, and i would do all the other suggestions before starting on this one.
-
It could be the head gasket or your head has become porous between the oil ways / water jacket, as your water system isn’t over pressurising… its obviously somewhere else rather than round the cylinders.
Whats the oil look like in the engine any water emulsion in it?

Mr Ballistic Oil looks ok looks really clean as I've done 2 oil changes in the 500 miles its been on the road using Fortee engine flush.
But no emulsion at all :undecided:
Monza you say you cant skim a 16v head should my man who is skimming know this?
I spoke to him and he said he will pressure test the head for £30 and skim for £30 did not say anything about cant skim the head on a golf (and he did ask what car it was??) If the head is porous will this show up in a pressure test?
Cheers

my valver head has had a light skim!
I know wat monza means though you can't take a lot off!
-
Just had a quick look through the history i got with the car and it had a head gasket done in 2004 and according to the invoice the head was re faced then so may be I will be better off not gettin it skimmed this time or say to the machinest check to see if its true and if its not then take off the smallest amount possible ???

If you have not used the car for a while, then I would continue to use it, albeit gently, and keep an eye on the water contamination, and oil level, until you are sure that either the oil contamination has flushed itself out, or you indeed have a problem. Nothing worse than doing a major job on a car than to find you have made no sodding difference.
You would be suprised where various fluids can get trapped and suddenly free themselves later. Also, if you had a problem with oil transfer, then more than likely, you would also get water transfer into the oil too. So keep an eye on that.
-
So what would you suggest then run the car for say another 500 miles then on the way keep checking the oil in the water as i have no contamination of oil what so ever empty out the coolant bottle every sign of oil ???

Yea, it could be oil left over from the your old leaking oil cooler (if it was leaking in the first place that is)
i would drain and flush your water system a few times and you will know if its old oil from your cooler if it dont come back.. (if you dont mind getting the ground dirty you could drain the coolant from the thermo outlet and leave the hose off. them stick the hose pipe in the coolant tank for a while :wink:.)
Its possible it could be a one way leak into the water system if its on the high pressure oil line.
i would take it off if its still doing it, get it warp and pressure tested so you know where you stand.. if you head is porous it will show up on a pressure test..
if your taking the head off yourself remember to soak the exhausts stud in penetrating oil / wd40 for as long as possible before removing the manifold..
Might be difficult to skim it again if its already been done once. Could get valve clearance trouble.. :sad:
-
Sod it i'm going to take the head off.. :cry: and see what i find.....
Report back soon....
Darren

Its off and there does not look to be any thing obvious so off to the machine shop Monday for a pressure check me thinks. :wink:
Darren

Well its now Friday and the head is back on, came back from the machine shop Tuesday pressure check all ok and re faced.
Ordered the head gasket set, 10 head bolts and a new cam belt from GSF, This all turned up on wednesday so back together it went oh and new injectors the merc ones from the ebay guy and new inj seals.
Finally got it finished and fired up on Thursday night. Within 5 min's the expansion bottle had a skim of oil so i removed the small hose from the exp bottle and let it run into an old coolant bottle so i c ould monitour the oil that was coming out from it but by this time it had prety much stopped so cleaned out the exp bottle put it back on.
Now i'm sure the head is ok I will drive it for 1000miles and monitour it......
So as a whole no closer to solving my problem but i've got a fresh head gasket as well as the other gaskets and a new set of injectors... :grin:
Darren :wink:

first head job (oh err missus!)?
-
On this car oh yes but I've probably done say 35 head gaskets in my time. (on vauxhalls)

well experienced then!

You could say that... :wink:
