Head machining

[roberth2013]

Put my 01 GTX back together today, followed the service manual,religiously,,everything torqued in sequence and to specs,, everything meticously cleaned,, started the engine,,let it idle about a minute,,started the water supply for cooling and to check water flow through the engine and see if i had water coming out of the "pisser,,previously had a flow blockage, overheating, had to relplace the head, exhaust manifold and the complete pipe due to saltwater corrosion,,been a night mare,
anyways,, when i was checking for water leaks with the engine idleing,,,i got some water pooling up on the head side of the gasket,, no leaks anywhere else,,,i sanded the head with a block and 32o grit paper,,,sanded the cylinder side with 400, just to clean up any leftover gasket material and clean up any residue i didnt use any type of sealer on the gasket,, the manufacturer said not needed,,, no leakage below the gasket, so im guessing the head might be warped.

can the head be machined? and what is the safest amount of removal before any interferance problems with the pistons bumping the head? any help appreciated thanks

It could be warped.... but you would have to check.

Pull it off, and put a straight edge on the head, and the cyl deck.

With the 951 engine... you will need a new gasket after you take it apart. And regardless what they say... give the head gasket a good coat of "Copper spray". I use it on ALL metal clad gaskets. it also helps seal a minor leak like what you are describing.

thanks i thought about it afterwards,,i should have used some layout dye and then sanded the head to check,,,and lke you i almost always used permatex copper spray or indian head shylak, on my quads and dirt bikes, but im new to watercraft, so i wasnt sure,, live and learn lol, i have already looked at your graphics,,,,i love the one with the skulls ghosted, do you have the complete set for my 01 gtx's
i was planning on contacting you about it later on, i have had a nightmare with these ski's and havnt started on the second one yet, i learned one thing,, when someone says ,,,oh they have only been in the saltwater one or two times,,,but i dont really know alot about jet skis, ruuunnn like your hair is on fire,,lmao anyways thanks for the input,, im going to pull the head back off tomorow and do some checking,,, let me know on the graphics
