anyone buy a used comlete long block form 928internationa
wondering if this is a better option than having head gasket replaced in existing engine(79).they say they do a compression test, all cylinders within 10% ,around 180 lbs ,and suggest replacing tb,water pump and oil pan gasket;with upcoming sale is this a worthwhile idea?
Not sure what I would do in your situation. It might depend on how long you ran/drove it with the bad gasket. I would think that if it was bad, coolant in the journals over an extended period could play on the crank bearings. Experts here would have a better idea.
If it wasn't too bad of a gasket failure, I would probably have the head checked for warping and then get the gasket replaced along with a tb/wp service.
Just my opinion and of course, there are experts here that will know better.
Anyway, if the question is about buying from 928 International, they are a trusted source for used parts. They only ship the good stuff and stand by their parts. So no worries there.
Good luck and would like to see how this plays out.
Head gaskets are made from a paper material. They soak in a coolant/water mixture that should have been replaced every two years to keep it from turning acidic and eating up the head gasket and the surrounding aluminum. This, obviously, didn't happen to very many engines. Every engine you find is going to have the same age head gaskets....with the same amount of deterioration.
I only purchase a different engine when the current engine has damage so severe that it can not be repaired.
Take it apart/have it taken apart and see what you need to do to fix it and then decide.

I purchased an engine from 928Intl on the very last day of their sale last year as I hadn't yet pulled the engine to diagnose my loss of compression in #8 and I didn't know what I would find once I opened it up. As it turned out "all" it needed was a valve job and the purchased engine is still sitting on a stand in the garage waiting for me to figure out what to do with it. Definitely take Greg's advice and figure out what you have before you decide where to start lighting stacks of money on fire, I wish I had gone that route myself but live and learn I guess.
I also purchased a used engine from them last year on the first day of the sale when my 84 seized from no coolant (long story) in October.
I tore down their used engine, replaced every gasket and seal, put it all back together with new harness, tbelt, water pump, ect. and installed it in my 84.
There were a lot of pluses - their used engine came complete with everything so for minimal added cost I have lots of spare nuts/bolts/fuel injectors (that would be sent off for cleaning before use)/distributor, etc.
However, I had a seized engine and cracked cylinder wall so I really needed a complete engine. If I only had a head gasket leak, I would be inclined to just pull the heads, check the block, have the heads surfaces (assuming the block is straight) and reinstall. I will say, the heads look like they are a PITA to remove with the engine in the car. I'm not sure there is enough clearance at the front wing (fender) to pull the head over the stud but I believe it has been done by others so get some input.
I bought one. Having a used engine sitting around in your garage all summer to tinker with getting it ready for a winter installation is a great way to learn how the whole thing works. It may not make sense from just replacing a head gasket standpoint, but very little I do on this car stands up to the harsh light or rational thought.

no better way to figure how something works than by taking it apart
last week i bought a spare Subaru engine with full intent to just flip it (it was so cheap, even scrap would make me profit) but i had the heads off and was poking around it that night just to see how things work...4-valves/cylinder but only SOHC...really cool wizardry in those heads.
I too bought a used engine before i pulled the one in my car. Whats different is that I got it on Craigslist for $300, delivered. No brainer.
I didnt need to replace my engine in car, i bought it for spares.
I tore down that motor first, as practice. it was nasty inside, lots of sludge, but otherwise ok.
Then i pulled mine about a month later. My in car engine had leaking headgaskets... I thought original and failing, which was not the case. Many other internal issues were found by me and by Greg Brown, who in the end completed my long-block full rebuild.
The spare motor donated many parts...which saved me alot of money.
