Paid $1,000 for this sucker......one of the best buys I've made. It supposedly had a blown 3.9L engine.
I bought this 2006 Pontiac G6 GTP convertible.......I didn't even look at it before I bought it.....The thousand dollar price was a killer deal........Anyhow, I thought all GTP models had the supercharger. But this car does not. That's pretty much the main reason I wanted the GTP version.Ok, so here's the story:
I see the car posted for sale on craigslist in the city of Sacramento......90 miles away from my house. I call the seller. She informs me that her husband looked at the engine and said the engine threw a rod and that the engine needed to be replaced.
I decided not to buy the car....an hour passes and I was just curious as to what the blue book value is on this car (I have never seen a convertible GTP until now). KBB value is $7,500......WHAT THE HECK!!!! So I call the owner back and say I will buy the car tomorrow. She says someone is coming to look at it in a few hours, but the first person with cash gets the car.......So I hop in my super fast Ferrari (AKA Scion xB Toaster Van) and I drive down to Sacramento and pay her for the car, telling her I will be back for it tomorrow and trailer it home.
The next day, I borrow a Suburban and rent a trailer............The Suburban has a busted tail light........on the way to Sacramento, I see an auto recycling yard along the side of the highway........I pull into the yard to buy a used tail light.......I look to my left and see a 3.9 Liter engine sitting there. Pure luck.
I tell the recycler that I want to buy the engine for this Pontiac G6.....the employee tells me it might not fit, and that I need to know what the engine code is in the car VIN number.........so, off I go to pick up the car.
On the way back home, I pull back into the yard with the car, verify that the engine will fit. The engine is from a 2006 Impala Super Sport, or maybe it was from a 2006 Malibu Maxx SS.....anyhow
I get the engine home, I have to swap over the oil pan, the intake manifold, the water X over pipe, the fuel injectors....couple other things.
I install the engine into the G6.......
End of story right?.......Wrong.
I am curious about the rod being thrown......I look and see no rod thrown. I see the oil pump is intact. I see the cam shaft is not broken. I dig a little more and I finally see the damage..........turned out to be the timing chain tensioner had cracked and there was no tension on the chain.....lots of slack.
I buy a new timing chain tensioner, install it, put all the old parts back on the engine: oil pan, intake, water pipe, etc..... I prime the engine block with oil using the oil pump.
I do a compression test.......150psi across the board.
Crank shaft endplay is good, rod bearings plasti guage within specs, looks like I may have a good engine.
