Oil for out turbo-ed engines

Hi folks,

What grade all do you pour into your T FIRE 8V engines? I am currently using Castrol 10w60, and I would not be asking this question at all, if not for one annoying clanking noise when idling on warmed up engine. Checked all I could (ideas are still welcome, but oil pressure is right, valve clearances too), and I am now slowly concluding this oil might not be that good of an idea.

/Woj

Yes, everyday use, no racing/track days, but any time I get a chance I like to kick the s..t out of it.

Re: Oil for out turbo-ed engines

10w 60 does seem a wrong choice

Is that recommended for this engine? what is recommendation for the 1242 engines? Maybe try that

Re: Oil for out turbo-ed engines

I use 10w40 semi synthetic... thats what the engine is made for as standard as far as i know.

the clanking noise might be the thrust bearing surface on the cam carrier. they seem pretty loose even as new. the came moves in and out slightly causing a tapping sound. annoying but harmless.
one of my heads is really noisy and i found out where it was from because of that head.
I "mared" the thrust surface (the cam carrier that the coil pack bolts to)and it made it a lot quieter... for a while.

Re: Oil for out turbo-ed engines

Craig mate, this kind of noise?:

It seems to be coming from the bottom of the engine, but then it is really difficult to tell.

Re: Oil for out turbo-ed engines

hard to say... try pushing and pulling the cam pulley in and out... i could feel/see lots of movement on the head i mentioned.


if you can it might be worth seeing if you can remove some of the play... what i was going to do was make a washer/shim from a coke/drinks can

you sure the sound is not your injectors?

I will have (yet one more) look at the cam, thanks Re injectors, 99% sure not, I can hear them separately. Besides, the behavior of this thing indicates it's lubrication related. For example, after a proper hard drive you stop to idle and it is silent for a long while (sometimes up to a minute), then it starts to kick in slowly to finally get persistent and loud. And only when the engine is warm.

Re: Oil for out turbo-ed engines

makes sense... the thrust bearing i talk about does not really get fed oil, it just gets what ever is splashed from the cam into the area behind the cam cover as far as i can tell.
well actually one side gets well lubed and the other side does not

Re: Oil for out turbo-ed engines

That's what you talk about? I guess for starters I can rebolt them to make sure they are torqued properly...

Re: Oil for out turbo-ed engines

yeh the one on the right is the one that handles the thrust.
you can take it off without removing the cam so you might as well check it out for yourself
