Engine Stutter Continued....

[spyder1529]

Hey, I posted a topic a while ago about an engine stutter. Recently the seller got it inspected, I don't know all the details yet but apparently "

2 cylinders are functioning a little above half than they should be

. " (the e-mail from seller) I'm pretty sure she's talking about the compression, but i'm not sure. Also what would be the best and worst senario, cost wise, to fix this problem?

Sounds like a blown head gasket, it probably blew between two of the cylinders. I think it's most common on I6 engines for it to blow between the 5-6 cylinders.

Correct me if I'm wrong here on this though.

I don't know how much it would cost, probably would be a little pricey cause it's a BMW.

head gaskets themselves are pretty cheap, but the labor to replace them isnt.

[Kevin325i]

Yeah and if you replace it yourself make sure you have somebody check to see if the head is warped.

We changed the head gasket ont his supra in my auto class..... the kid blew the engine the next day. One of the reasons was a warped head that they figured would be ok.

Also doesn't BMW use head bolts that can only be torqued once? So you'd have to make sure to get a new set of those.

Indeed, always change head bolts when replacing the head gasket!
