Ive got leaky cam seals and need to identify if my head is 2wd or 4wd as the oil seals are different.

I know 2wd are supposed to have turbo hanger lugs but they sometimes get machined off.

Any way of telling which is which??

 

4x4. if it was 2wd, you'd see where it was machined off, but cant see anything in those pics.

 

I'd say that's a 4x4 one mate, you can tell when the bracket has been machined off even if it has been done really neatly like mine.

2wd has 2 bolt thermo housing and 4x4 has 3 to the head, looks like a 4x4 but pic not great.

 

Saff 4x4 to me

 

My 2WD head has 3 bolt holes for the thermostat housing.
Rich

 

so looking like 4x4?

anywhere i can photo to make sure??

 

Oil feed for turbo is in side of the head in the middle

 

Thats the easiest way to tell

Steve

 

As said, the oil feed in the middle of the head on exhaust side. Sometimes gets blanked off with a bolt though, like mine. I still use the 2wd feed even though I have a 4x4 head.

cheeRS

 

so is the oil feed above the exhaust manifold then??

 

Isnt the temp switch located at the rear on 4x4 and at the front on 2wd?

 

The blue ECU one or the guage one?? The blue one is on the rear of my car.

 

The guage one. Suprised its not been mentioned which makes me think im most likely wrong now pms lol.

 

it is a 4x4 head.

Temp is located front left 2wd rear right under the cts on 4x4

And i think the cts on a small turbo head is on the front right inlet side.

Only very early 2wd heads have 2 bolt thermostat design.

these are some i had

might help

 

cool costina. I shall take another look in a bit but it seems 4x4 from what your pics show. Don't want to buy the wrong oil seals!!

 

deffo 4x4 warren
I've had a few lol, are you sure its leaking from the seals? just that they can leak from the bearing carrier joint to head where people forget to seal if they have had the cams out.

 

im thinking its more likely the crank tbh as thats where all the oil seems to be staining. If its leaking from the cam cover joint then its too small to be noticed on the drive to and from work today as i cleaned bits off with break cleaner to see where its coming from.


but if im going to have to replace the belt then i might as well do the seals while im at it. That way i know its done.

 

front crank seal ?
check what i said while your at it aswell.

 

where would it leak if it was the cam carrier? bear in mind my cams havent been touched in 15k miles and the leak is recentish. would it just piss out the front between where the half moons go??

camcover was done 6 months ago by someone i trust so i doubt its that.

 

where the ends of the half moons sit thats where the joint is many people assume its the half moons when infact its the joint. to fix remove front cam bearing carrier tops fully clean head and under carrier clean rubber O ring and reseal carrier refit and torque to 10nm

I can do you pics of area if you need them tomorrow

Paul

 

so if it leaks there it will blast past the half moon and a ton of tigerseal then??

 

If its leaking there it wont be what your man has done cos tiger seal sticks like shit to a blanket it will leak from the side of it.

I will take a pic tomorrow it will expalin it a lot better

 

ah ok cool.

 

Here are some pics This is a 4x4 head

Hope this helps.

 

Awesome costina! I know where you mean now.

Need to stop the leak as the oil is going fucking everywhere its only loosing a litre of oil per 1000 mile so its not too bad now but before i was only burning a few hundred ml per 1000 miles about town and less on long runs as its only 15k since rebuild so hardly worn out really.

Most annoying thing is it runs down the block, then when rad fans come on blows it rearward on the block and onto my downpipe which is covered in wrap so when i run the antilag it smokes once red hot as the oil burns off!!

Oh and ive renamed by car the "torrey canyon".

 

No worries hope it helps i've also found that the cometic cam cover gaskets are very very good and thats all i use now. but i would recommend not to use tiger seal with them try innotec sealer thats very good and it wil peel off so u can reuse gasket if need be.

Paul

 

I just hope its not the headgasket

I have headgasket paranoia since ive had a cossie Especially as the car has coopers rings so is silly expensive to do a head gasket.

 

Yeah i can understand that ive a block that requires coopers rings gasket but tbh there pretty good.
looking at your pics the oil which is all above the head gasket looks fresh and coming from cam cover/seals area.

If your doing it yourself this time ensure the cover face is flat and that u torque up the cam cover bolts starting in the middle working outwards same as head bolts torque to 10 nm.

 

Ł165 for a coopers ring head gasket now mate so not as bad as they used to be, my engine that Tony has built has one hence I know the price.

Steve

 

Steve, do you know the o/d of the ring buy anychance?

cheers

Paul

 

I think the casting numbers for a 2wd start with 86 and 4wd 89 or 92, I may be wrong but thats what i have seen on mine as i have both.

Steve

 

is that including the new fire rings steve?? if so thats not too silly and i might buy one to keep "in stock" in case i ever need it.

Its one of those things that if i have one on the shelf, then i wont have to use it

eg i had a phantom water leak middle last year from the waterpump area. it was even pissing out the tell tale holes top and bottom - classic water pump death.

Literally as soon as id ordered a new pump, the leak stopped new pump is still in the boot and its not lost a drop of coolant since then

fucking cossies

 

Sorry mate I dont, I had to source one for my build and once found where to get them passed on the info to Tony and he dealt with it from then on.

Steve

 

Yes mate complete.
