Hi
Need some serious Help, sorry that we had to meet that way but no choice ,my problem is pretty serious ( I think) since im french from Quebec (Canada) please dont be to hard on my grammar, here is the issue. Just change the engine on my MCS 2002 ,put a rebuild S/C from Eaton plus all the parts around.After my first drive (took 9 month)I was in HEAVEN , but after checking under the hood my oil was creamy and over the line.Here some info Comp #1=135 psi #2=125 psi #3=120 psi #4=130 psi. the plugs and piston were dark so that looks all right to me.Thanks for the feedback.

 

Well Milky oil sounds like water.

If it truely is anti-freeze it is your head gasket usually.

but you may want to have the oil checked out then.

 

How many miles do you have? It is not always the head gasket. When I got my car, there was a gnarly milkshake situation going on, swapped out just the gasket, same deal. New head was installed and no more milkshake. (my car had 104k miles when the milkshake scenario was noticed, and its a 7/02)

 

Hi 56rfixr

After some search I will be doing a leak down test. Hope your wrong about the
head but will keep you posted

 

Your heat exchanger might be faulty. A small crack can lead to the symptons you mentioned. It's quite a mess to clean up. It's a common error on the R53.

Since all the faults are pretty pricey, the help of a pro might be a good buy to diagnose the issue....
Most common issue is a head gasket I think...
But a cracked head can cause the same issue....you can check for both at the same time..
The cracked oil cooler is possible, but I think the cracked block might be slightly more common....
In any case, antifreeze is very bad for bearings and other engine internals that are usually bathed in oil....so park the car, and if it must go any length yo get it fixed, tow it.

 

Thanks for the good reply guys, be sure that the car is park until the problem is fix.Big thanks for the topic, if its the problem(oil cooler) their a big beer on that
one if your right.Just got my rig to check for the leak,. probably tomorrow kind of poup for today.

 

Wow Hurray for the internet (forum) right on the button here are the result after a leak down compression test ,the experience was cool but the result was a kind of s$#@@@#$ , at a 95 psi test here are the result #1-90 PSI #2-65-
#3-65 #4-90 PSI , no bubble in the expansion tank. So s&&^%$$ probably a head.

 

Head probably warped. Did it overheat on you recently? Let us know what you find after removing the cylinder head.

Hi
Unfortunatly the head is crack between the timming chain and the piston head
so need to order gaskets and find a head

 

There is one in the Marketplace here

 

Thanks for the input just send him a Email. I was wondering if its the same core
for a MCS and a non S. Saw some nice head on ebay.uk wrote a email to the seller for the cost of shipping.

 

Just change the head this morning and the problem is solve

 

Glad it all worked out. It's strange that the crack was in one of the cylinders that had a good leakdown test reading, though. I was expecting something between cylinders 2 & 3 - either a crack in the head or a rupture in the gasket.
