He also installed an aftermarket coolant filter.
Im not master mechanic by any means, but here is what I know from reading over many posts on this forum. Is this guy running a tuned truck and really beating on it hard? I have heard many guys on this forum say they have NOT had head gasket issues because of the somewhat gentile way they treat their truck. Hard pulls at each stoplight on a tuned vehicle will eventually wreak havoc on it, but I bet you already know that.
1)When doing studs, the vast majority of users buy brand new OEM head gaskets. I have read some posts about issues arising when the black onyx (i think thats the brand) gasket is used.
2)If it is coolant he smelled and saw under the hood, doesnt automatically mean it was a blown head gasket. Could be from a faulty EGR cooler or could have come from the degas coolant tank and be a bad coolant cap.
3)Nothing wrong with an aftermarket coolant filter. A lot of truck owners have this on their vehicle as added piece of mind. Just helps remove any contaminants that may clog up the oil cooler.
This is just my two pennies worth of what I have seen on this forum....Hope it helped
