I'm about to call the mechanic for update on my engine. First I need
estimation from someone outsider, for how much it takes to open and change
the other cover isolating device (what you call it?), if the other cover
has already been opened and the isolating thingy been changed.

Since all the common things have been already removed, I suppose it
shouldn't be that much extra work, but the mechanic estimated quite
surprisingly amount of labour for changing both, instead of one.

I'm about to get that information, but it wouldn't hurt if here someone
who has changed the thing in V-engine, told how much he estimates the
labour from professional mechanic.

 

I'm coming in at the end of this. There's a pressure relief valve in
both heads. Twice I have seen a problem with them. One fell out, it
was laying under the valve cover when I removed it. The other simply
stuck wide open, no pressure to the top of the engine, all the oil
blew out the valve. Both were a pretty cheap repair. Good luck.

 

Ok, hopefully this is my final post around this issue.

I got the car back yesterday. The mechanic had opened the cover (gasket?)
of the non-oiled V-branch. The cover insulating-thingy (you haven't yet
told me the correct term for that part) has these holes in it, and then
there's this quite narrow bridge combining two of the holes. The mechanic
had found clog in that narrow bridge, and after replacing the thingy the
engine has been running perfectly. The clog was this black debris which
gathers in the engine if you don't rev enough from time to time.

So it seems, that now the engine is fine. I drove the car around somewhat
yesterday, and today to work, and I surely hope the failure doesn't come
back. One thing to notify, since the lifters have been changed, the engine
is more quiet than most of new cars I've driven. At traffic lights, with
neutral-gear on, I had to turn off all things including A/C+fan, and still
it was hard to hear if the engine was running or not.

As a pre-empitve strike, I suppose I should have the other V-branch cover
opened and the isolating-thingy replaced. I've been told that they should
be changed every 100k miles, and most of the cars around here are driven
at least 200k, many even 300-400k, so there's still plenty of changes in
the future to come.

I did ask about the oil pressure during the test, the mechanic said that
the pressure was around 5 bar (~73 psi) at high rpm. I guess this is ok
(or good?) result?

Finally I can continue enjoying driving nice car, and listening sound from
Bose-system. I've have had a little bad luck with previous cars, I hope I
can now rely on this car.


Thanks for everyone for comments, good to know that if there's going to be
any problems, I know at least one place where to look for expert tips.

BR, Tero

Please explain where the "insulating-thingy" is located and how it
looks. Is it the rubber or cork seal that sits between the cylinder
head and the valve cover? That is a gasket ("packning" in swedish).

Cheers,

I suppose it's that cork seal between the cylinders and the gasket.

To make sure: It's about 30 cm x 12 cm (12inc x 4.5 inc), about 1 mm thick
(or 2), has three big holes for cylinders, and many smaller holes for
other channels, oil as a one (or more). I know what it is called in
Finnish, but that doesn't help you that much. I suppose direct conversion
from the Finnish word would become "Gasket insulator".

"Cylinder head gasket" or simply "head gasket" in American English

That sounds like a head gasket. It's the thing that sits between the
cylinder head and the engine block and seals the combustion gasses,
coolant, oil.

The HEAD gasket was "clogged"????????

Now THATS different.
