Doest it give a bigish puff of oil when you start it up in the mornings / or after its been sitting for many hours ?

 

I personally think it may be rings; by the small description thave you have given.

 

Quick fix - another 4ac.

rings are... so so, pull motor out strip off the head pull rods and pistons out... ect ect. carnt imagine being fun of a job if your in a rush to get it back on the road. I don't know if there are any other ways but I'm sure there is.

Reason i say the does it do it when its been sitting yada yada - Gives time for oil to seap past the valve guides, and sit on the back of the valve or inside the combustion chamber, dependng on where the motor stops. So, when you start it up, if its a ploom of smoke, then it goes away, thats usually the problem. If it keeps smoking while ure driving - its either rings, or very badd valve guids.

 

Its cheaper to do valve guides.. kinda.. take the head off and valves out - replace the guids; (motor in job)

 

Rings - well, yeah motor out start again roger type thing..

lol..anyone can bag a 4AC or a 4KC, but at the end of the day, diagnosing the problem, fixing it is more of a solution then talking about an oxy. ;) :P !

Teddy is on the money with the valve stem seals, I probably have a spare 4A-C head, Just throw in the HPR30 and see how it is for a quick fix.

Yeah, I'll give the good oil a go first, if that clears it up sweet, I've got a new filter as well.

 

If I have to to pull the head off, then I'll give it a go and maybe investigate a cam grind.

 

Cheers for the help
