Thread: 3.0 TDV6 broken crankshaft / engine rebuild

It's mentioned in one of the diagrams for the 2.7 to use sealant in the corner of the cam caps, only for the exhaust cams.

Photos of the mist and location? Get someone to stall the engine up for you.

You're right, thank you!! Replacing the brake switch solved the problem of the above-mentioned errors. thanks again for the advise. As for the mist I mentioned, it hasn't appeared again. Even when turning the engine revs, I couldn't see anything. The car has done another 200km since then and I started to investigate. One thing's for sure, what was leaking is not engine oil. What is leaking is the fluid of the power steering system. It's leaking somewhere around the power steering pump, but somewhere behind the pump in the back.

Aren't the lobes the bulges on the cam(s) that push the valves down internally?

Machining buttons yr thinking of maybe?

FFS. The end of the cam where the cam cap fixes it to the head and the intake manifold steps over.

In my day we called those journals.

Hello everyone,
I haven't posted in a long time, but I'm freaking out…
I have a problem with leaking oil all the time. At first I thought it was the power steering pump (I removed and replaced all seals). Unfortunately, wrong diagnosis. Then I took off the inlet manifold and installed a new gasket plus silicone where it should be plus a little more .... again bad diagnosis..I realized that the leak is from the front left bank cam seal. I replaced it, went to the car wash to wash the engine.. I'm going home and I'm looking under the engine.. and unfortunately it's still leaking and everything seems to be the same seal . I will add that after replacing the seal, I started the engine for some time without the timing cover and I did not observe anything at all. I'm considering options somehow the pressure in the head increases and throws oil. I will add that I have already driven 4000 km and the engine shows no suspicious movements since the rebuild, no alerts or engine errors even on IIDTool.

Why not just take it to someone who knows what they’re doing and ask them to correctly diagnose the issues???? Then if you’re cheap, fix it yourself. Stop guessing
