I've got a 3.4 sitting on my carport. Been there about 4-5 years give or take. Never been rained on or anything. It had a bad freeze plug when I bought it, never heard it run. But was told it ran good. Don't know the mileage either. Should I pull the heads for a look or leave it as is ? And sell it. What's the going price now days ?

With so little known about the engine it's going to be a gamble for anyone to put it in their car.

I could see if i can borrow an inspection camera, pull the plugs and have a look. Maybe hook up a compression tester , put on a starter and see the results.

No need to pull the head ,,a compression check will tell you all you need to know ,,only a complete tear down
wiil show if the engine is good!! ... If sitting for over 2 years spray some lube in the cylinders ,use a can that has a fog spray
first turn engine over a with breaker bar !! THEN, using a battery & turning the engine over without it cranking will be sufficient ..doing this will show the engine is better than 90% of the engines from a junk/salvage yard..its a big plus if the engine is clean & the buyer does not have to pull the engine
& he can watch & listen to it turn over don,t know whats wrong with my new girlfriend ,at least I do not have an engine in the living room..

Don't just turn that engine ove. Pull the distributor and modify a old distributor (remove cam gear) to spin the oil pump with your drill.

Make sure it has oil that is clean first.

Right now your bearing are dry and prob have a coat of nasty residue.


This won't take long to do.
