    That doesn't really seem very abnormal to me. What made you check?

    Was the engine hot when you took this video...?

    Will I'm getting check engine and hi temp. But that's coming up when the engine just starts up. So are you saying it may not be a head gasket the compression is 130 120 120.

    You sure it's the engine overheating and not the exhaust?

    I cant really say that a bad headgasket affects the compression very much but your numbers are low reguardless. when the antifreeze warms up it expands and with the cap off it will overflow. Im not saying you DON'T need a head gasket but if your headgasket was allowing exhaust gas into the cooling system, it would force the antifreeze out of the clear tube even when the cap is on.
    Common Head Gasket Symptoms (one or all of the following)
    Antifreeze in the oil
    Oil in the antifreeze
    burning oil
    burning antifreeze
    excessive blowby
    overheating and excessive air or pressure in the coolant system

    I had a head gasket go bad on a 215hp jet boat. took it for a ride with the hatch open. As soon as it built boost the antifreeze sprayed out of the clear tube like a fire hose until it overheated the motor

    Not shore. Trying to buy the cam doo setup now, hopefully that will tell me I hope

    No I haven't had that with the cap on. Or any of the oil in this and coolant in that. So your saying my compression won't be that good if it was a head gasket.
