Engine problem

Post by marcus » Fri Apr 19, 2019 2:22 pm

Hello,
I have S60 2.4 170hp. 400k mailes. Since last year I have new engine. I was informad it has 120k mail. Indeed it was in good condition. I noticed very low oil consuption. So the milage could be trouth.
Since some time i noticed rutling sound at higher rpms -3500. I was not sure what it is. It sound like some metal cover would be loose.
But today traveling at 50 mph my engine stoped suddenly. When I stopped It could not crank. I was thinking that buttery is down. Could not make single crank.
I was waiting for towing maybe 1.5 hr. Then I starded one more time and eningine started. Just after it started I heard some gurgling sound. From behind stering wheel it sound like a head make the noice. I stopped it suddenly. I was trying to start it one more time at home but had the same results. Engine was running with strange noice.
Oil and coolant was as it should be.
I did check the timing which was correct.
What can be a problem?
I already taken down the head cover. I pushed all valves and they seems to be moving as they should.
Please advise what esle I can check?

Removing the cam cover is pretty extreme. They dont just jump back on there. dont crank the engine with it off. There is no way to diagnose it now. This may be the end unless you are up to replacing it. decide weather you can do that and then we can chip away at
what it could be. sounds like the head gasket failed enough to fill a cylinder with coolant, but you should have seen some change at the reservoir. also did you check all three timing marks, not just the two cams?. the cams can be in sync but the belt on the crank gear jumped. The very first thing after check timing is a compression test, but you cant do that with the cam cover off since it it the bearing for the cams.

I did check all marks.
I can make the test presure now. All valves will be in closed position. No colision with piston is possible. Or you had another points on mind.

The numbers will be low since the intake won't be open, but it will show if one cylinder is bad. also you may see coolant spit out a spark plug hole. If you dont have a comp. tester now, you could turn it over with the plugs out and see if its spitting coolant.

I put back the cams but could not start the engine. No idea what happend. Did put back everythink.
Refering to the first topicc could it be that the enigne stoped due to lack of lubrication or was overheated? And started after colled down?
I did not do yet the compr test.
