You win....

Paraffin it is....  

 

[CaptainZok]

Told ya, iespell to the rescue again.

I have done that in the past using petrol instead. What are the viscosity difference between paraffin and petrol?

Seems to be a tough one to answer......the info I found suggested that Paraffin, Petrol and Diesel (crude based) are all similar as they have viscosity modifiers......to thin and they are difficult to inject and cause clogging, to thin and you get leaks.......

I use paraffin as its a little less volatile than Petrol.

Gasket kit has arrived apparently so the head re-builds can start tonight.

[Marks DTM Calib]

Head re-builds went well....a few inlet valves short so they are being delivered tomorrow. Both are cleaned and pretty much ready to go.

Coolant pipe to thermostat mounting bracket broke when removed so another one ordered, should be here tomorrow.

Matchless popped around and managed to get the engine stripped to the cams.

So tonight its off with its heads.....and maybe re-seal the oil cooler plate.

Mark, on the oil cooler sealant - easy around the edges with it or "apply liberally?"

Good to see its all going well, so far  

[Marks DTM Calib]

Its difficult not to apply liberally as its that dam stiff!

So yes, apply liberally, you need to fill the casting groove in the plate as a minimum plus some additional.

Mark,
in generall how do you find the valve guide condition on the high milleage v6 heads? Are they usually good or the valve is very loose? i'm really curious as i will be doing my heads at some point.

[Marks DTM Calib]

Wear appears to be pretty much zero.....no sign of any wear (these were 138k mile heads), certainly no slop.

Valves also clean up easily and again show now major wear.

You can see some wear on the cams (very minimal) and a little on the follower bores (again minimal), piston bores are also spotless.

It seems that these engine do last very well with good servicing.....

Mark,

Are the heads the original ones that were taken out when you put issunaz's ones in?

If so, be interested to know what the state of the valves were?

Cheers
Merv

Thanks and regards

6 bent inlet valves on 2-4-6 cylinders.

Leaking exhaust manifold gaskets (both banks)

Do you still need that condensor mate, in light of your prang?

I think that might now be surplus to requirements thanks.....

[JamesV6CDX]

I guessed as much

All the best with the rebuild, and keep us posted on your progress!

Kostas,

Sorry, Didn't mean to ignore it, it was ages before I went back on to the messages due to work being really manic at the moment,  I was then waiting for a call back from Mark to see what he wanted to do and basically forgot!  

Apologies to anyone else I have inadvertantly ignored,  it was not personall or really intended.
