First off - I know this shouldn't be in GD but I need a quick answer.

1994 Volvo 850 Turbo

It was having a battery drain issue (------- glove box light) and so if the car sat for 2 or 3 days it would drain the battery. Normally it's not that big of a deal, just jump the car and it's good to go.

Well, I drive it home from college and borrow a parents car for the week so I can bring all my ---- home in 1 trip.

The car sat for 2 or 3 days and then wouldn't start. When it was hooked up to jumper cables it just cranks and cranks and doesn't kick at all.

I checked for fuel and it was there, checked for spark and didn't get any but the shop I ended up taking it to said they were getting spark...

The shop I took it to did a compression test and said they have about 60psi across all cylinders. The first thought was that the timing belt jumped a tooth... but supposedly the timing is on.

So, how the ---- did my motor just lose all compression by sitting around? When I parked it the last time it was running it was working fine.

 

throw some marvel mystery oil in the cylinders and let it sit for a little bit. if not the rings then i think with hydro lifters they can drain and not work right.

 

maybe the shop is ------- you over?

could have been something small.

 

I don't think the shop is ------- me.... We've worked with them before and the owner is a good guy. I'll have them try putting some oil in the cylinders.

 

996 turbo's have been no to have a no start condition if you use anything over a 5w-40 oil. Something about lifters bleeding down. Not saying this is your problem, but it can happen.

Id get em to double check the timing. The same compression across all four suggests either their compression gauge is broken, or its out of time.

 

who said the motor blew in one day. it probably has .001 psi less compression than it did the week before and it was the straw that broke the camels back.

 

Well now, there's your problem. Can you wrap your mind around it?

At this point the plugs are dead. Fresh plugs, pull fuel pump fuse, run motor on ether/starting fluid to dry it out. Put FP fuse back in while she's running on ether. I do this a lot for a lot of cars.

 

If that shop doesn't know a flooded engine has shitty compression, you need to find a new shop.

 

Lol.. a flooded engine will get higher compression....

 

ever done a compression test on a cylinder flooded with gas? Its not like oil :1
