Identifying cavitation with heads off? Now with PICS!
Yes essentially they're just a stretched 1.6d, they share most bottom end parts and valves and such. Very cool little engines, be great and rev over 5k! I will look into the idi turbo gaskets and probably just leave everything stock for now and see if the engine runs without using coolant. If...- volvo 4 life

I'll try and keep the thread updated with my progress and what I decide to do, should be interesting to see the results at least! Thank you for all of the help so far, this has...- volvo 4 life

Identifying cavitation with heads off? Now with PICS!
Even with cracks past the fire ring you think the head gaskets would hold? That's what I'm really concerned about considering the high compression of these engines. I can get all of the pre chambers from diesel cast for around $120 + shipping, but supposedly the heads will have to be skimmed...- volvo 4 life

Identifying cavitation with heads off? Now with PICS!
So with cracks like those, how nervous should i be if I run it NA? It seems that these pistons can take a serious amount of abuse and rarely if ever, suffer catastrophic failure. A friend of mine just did head gaskets on his 6.9 and the tops of a couple pistons looked like they got shot with...- volvo 4 life

Here's the pictures! And those are the worst of the 8 pistons, the other 5 are cracked but not as noticeably.- volvo 4 life

Identifying cavitation with heads off? Now with PICS!
I looked at the pictures I have of the pistons and the number stamped in the top is 1816562c1 and there is an uppercase A stamped just outside of the bowl cutout. It is a serpentine belt engine so it's at least a 1992 and from what I can tell it is definitely an NA engine. There are no dimples...- volvo 4 life

Yeah I agree, it had to be abused pretty badly. It supposedly had an 093 turbo on it that the kid removed and used on his own truck so it was probably turned up without an egt gauge and ran hard. Sucks to spend money and end up with a piece of junk- volvo 4 life

Identifying cavitation with heads off? Now with PICS!
I'm trying to get my photobucket account email figured out, I haven't used it in years so until then I guess I can't post pictures but they are cracked in multiple spots. I don't know what this engine went through but it definitely got hot. If the block is deemed to be useable by the fact that...- volvo 4 life

Identifying cavitation with heads off? Now with PICS!
Hello! I'm new to the forum and recently picked up a 94 7.3 idi that was listed as a factory turbo engine. Turns out that based on the harmonic balancer and exhaust valves, it actually appears to be a naturally aspirated motor and one that was beaten pretty hard. All 8 pistons are cracked and...- volvo 4 life
