Just did a major surgery on my 4G64 engine on my Mighty Max..... Replaced HLAs... 2 Timing belts, tensioner..camshaft seal. Valve stem seals(what a pain)..water pump..radiator.valve cover gasket..spark plugs....etc..

It had been burning and leaking oil for 3 years... but it was running strong...i just checked and added oil frequently to keep it running..

After i replaced all the parts listed above... the engine runs perfect..no burning oil at all....no matter at start up or high rpm....

Now i am thinking of getting rid of the carbon deposit that accumulated over the years.... any experience on that?
I know seafoam.. i poured a little bit into throttle body.... Just wondering if there is any better or proven way to get rid of the thick layer of carbon inside engine...


Thanks in advance..
