Which oil ???

TrishP,

any 10w 40 or 15w 40 Diesel engine oil will be fine. I noticed that Vanellus Global is a 10w 40, which shouldnt make to much difference, just not as good in colder temperatures on start up. Otherwise, I could not see it as cause to be blown out of the breather tube.

First thing to check may be the oil level. Check it isnt overfull, as the excess oil would have to go somewhere, and a breather tube sounds like a likely candidate. I know that the manual says to fit 6.5L, but ive never fitted that much in. There always seems to a bit of residual left in the engine.

Otherwise, Im out of ideas. Good luck

Mike

First thing I would do is get it compression tested

I'm no expert but from what I have been told is that if oil is being blown back out anywhere, then you have a problem.
If you have a positive crackcase ventilation system, ( not too sure ) then check it to make sure the valve is not stuck.
Are you using the recomended class and viscosity oil ? as per the drivers manual !
Apart from that I cannot offer any advice, except to take it back to the people where you had it done, and if you did it yourself then you may have got something wrong somewhere.

By chance was the original pistons used, and maybe one has a hole in it.

Did you check the ring gaps ?
I'm not too sure what they are supposed to be, but just a little over could be detremental

Did you get just one of the rings in the wrong spot ?
Or did one ring crack during installation ?

Were the rings correctly rotated, ? ie one piston may have ring gaps down 1 side, there is a correct position for them.
I wish you luck and please let me know the prognosis !

There is quite a bit of info on all things Rodeo (Isuzu) on www.clubisuzu.com
You could do worse than tour through thier website.

Although I prefer not to use a synthetic oil for the run in period and only use a cheap oil it should not matter as a lot of car manufactures use it from the factory, but in saying that if you baby'd the engine or let it idle too much the bore could have glazed. There are products available for deglazing if this is the problem.
You say you have cylinder liners with chrome bores are you sure that the rings were not chrome plated as well? chrome rings can never be fitted to a chrome bore.

You mention that your cyl liners are chrome. Is this the overall type of metal of the liner or does the liner have a chrome bore? If the latter ,did the pistons come with chrome plated rings especially the top rings? If so you have a problem as chrome rings cannot be run in a chrome bore. Hopefully this is not the case in your instance, but chrome rings will not bed in a chrome bore. Just a thought . Regards G.T.
