I will check the head for flatness tomorrow hopefully. I did get the head as clean as I could. Are these tiny scratches any issue? (mostly concerned with the one near the water jacket)

Pulled the head this morning. What does this look like? I didnt clean the old gasket material off last time? Didnt torque the head bolts down enough?? I have new gasket on the way along with ARP...

ive got a new oil cooler on the way. also going to replace the head gasket again because i may not have cleaned the mating surfaces well. this seemed like a large amount of coolant.

the weep hole...

you guys think my oil cooler is bad???? It did hold pressure on the coolant side seemingly. also all of the plugs were white like this one.

I have a 2010 GTX 155. last year I started to notice that the oil filters were being collapsed in on themselves after I changed the oil. I did some investigating and found coolant in the oil. No oil...

i'll echo spook's reply, with proper care and maintenance you wont be able to tell the difference between a salt/fresh ski regardless of hours. my example is I bought a salt ski with 239hrs last year...

you were on the right track and helped me figure out the issue! I had installed the intake manifold incorrectly. it was not sitting on the lower rubber mounts causing a huge vacuum leak between the...

ive got it all reassembled. turned over the engine several times without the plugs in and it sounded good. I put the plugs in and connected everything, started it up and it shot to ~4000rpm for a...

Took some photos of the valve cover vent valve thing. this is def coolant mixed with oil in here. Hard to see in the photos but its a green with coolant smell and taste.

Also some bonus photos...

Thanks for all of the info so far. I was able to get the gear and chain on what looks to be the correct position. I took the locking tools out and was able to rotate the engine over by hand several...

Coolant level was fine, i changed it once last year. ive owned this ski since feb 2020 and bought with ~239hrs and it has ~270hrs now. Never had an issue with overflowing or losing coolant. Ive had...

Where else could coolant be entering the oil? I did run a straight edge over the head and it seemed good. Ski never over heat in the year ive owned it. the oil cooler looked alright from the outside,...

Oh crap does the cam have to come out to get the gear and chain back on? I kept the cam, rockers, valves and everything together since there were no issues there.

Thanks, I was hoping to get by without torquing the head bolts down to assemble the cam gear and timing chain and rotate the engine over to make sure i had the correct timing. I do have the head on...

Here are the front and back of the old gasket.http://greenhulk.net/forums/attachment.php?attachmentid=472008&stc=1http://greenhulk.net/forums/attachment.php?attachmentid=472009&stc=1

anyone got...

Yeah there is some coolant that fell on the cylinders from the coolant hose had some drops in it. I'll grab a photo of the front and back of the
old headd gasket today.

The ski did have two...

thanks for the suggestions everyone, got the head off. What say you guys, is this head gasket bad?

I wanted to post an update, went out at lunchtime today and moved the waterbox and related exhaust tubing components to get better access to the driveshaft. I was able to get a good grip on the nut...

I have a 2010 GTX 155 (no supercharger). I am replacing only the head gasket (some other gaskets while im in there) and wondering if there is an easier way to spin the engine over by hand to lock it...

fyi, you'll need a way to plug the holes in the pump tunnel left by the ibr brackets.

Last update! Water tested it yesterday in the freezing cold. Totally worth it. IBR worked perfectly. No more play in the bucket mechanism since I replaced all of the bushings as well.

As an added...

Wanted to give another update. Got all the parts in and assembled. Other than a dead battery the ski starts and runs great. The IBR functions like normal, so far (no codes or lights). Ive only tested...

Just wanted to make an update in this thread. I ordered a new IBR from partzilla, it got here yesterday and I tested it this morning. With it connected to the ski I was able to wake the ski up, turn...

My ski does see exclusively salt water. I keep up with the flushing/washing/rinsing after every ride. I did purchase it at ~230hrs and the previous owner never rinsed it and let it sit in the water...

Im working on the IBR of my 2010 GTX 155 and noticing a couple of brass nuts on the IBR bucket and just on other parts of the ski. Is there any harm with replacing them with stainless steel (provided...
