RE: Volvo 944 Former Police Car - Dedonutified
Time for an update!

Engine is alive, up and running!

Got a problem, the inside of the valve cover was completely covered in some sort of white goo, no idea where it´s coming from..
Dismounted the oilcooler but with no success, total run time is about one hour now, and I´ve swapped the oil twice and now it is only on the inside of the oil-fill-cap, it becomes clear white after approximately 15-20 minutes of runnig.

Sparkplugs are black (running really, really rich due to leaking downpipe) and all header pipes as well (so no leakage from the head gasket to the combustion chambers) cooling aid is clear blue and the oil is not brown or white on the oil level control stick.

Both the block and the head is in level and new gaskets in the whole engine, could it be chemicals from the engine cleaning?

Help is deeply appreciated
Peace out!Fingersx

Sounds like head gasket has a slight leak.

I would suggest checking the head for a crack. I had a B20F that was a fresh rebuilt engine and it had a crack inside the valve cover making the inside of the valve cover white goo. We found it with a pressure test and it puzzles me that something didn't show up for you but maybe try the pressure test with the valve cover off?

Where was your crack? Between the valves?

Success!!

Were out on a real test drive, at one bar unmapped ecu, drove for about 35 mins without any problems other than some oil leaks from the valve cover (worn, broken gasket). No more white goo in the oil cap, so I suppose it was left over water from the cleaning Big Grin

Though it's running pretty rich at idle, about 0.89 but I think it is due to a leakage in the exhaust header Dodgy
If someone's interested I could upload a log file when it's mapped and ready to plague Headbang ?

Well, maximun power is not my current goal, but I think it's capable for around 350/400hk if I run it on a lot of ethanol and 2bar pressure ^^

For now my goal is to get everything to work perfect, seems like I've got a crack in the cylinder head...Dodgy

Yeah!
I was thinking of stealing the lifters and the camshaft from the old head... but then we must do a new VE-table.. again Catfight xD but with the tank filled up with alcohol and a pretty mean camshaft we should be able to load 250-300 kpa Headbang

So what's next? Did you get final dyno numbers on what it made?

Next's up is ethanol, starting tomorrow. To high compression ratio+95octane+lot's of load = Chainsaw

Started to detonate/knock (don't know the english word...) at 4000rpm so that's the reason we didn't go further (plus we maxed the bench Guitar )

So this week I'm planning to roll up my sleeves and go ethanol! Hopefully we can violate the engine enough to get some numbers before rods starts to peek out the block Fingersx

Here we go again!

Drove the car about 10 hours last week, everything works fine!
Although there's many small details that must be fixed, got almost 50hours to spend at that this week, so hopefully I can take it to a real test drive in this weekend.
