Chris_Austria Posted September 30, 2010 Report Share Posted September 30, 2010 Hi! I tried to tighten the screws of my oil pan.. with success except of one screw. I couldn't tighten it and now it's broken. Don't leak more than before (maybe it's even better.. afte 15 minutes idling the engine there is no leak) Can I get the remaining part of the broken screw out, drill a new thread and put another screw in?

Ranger Posted October 1, 2010 Report Share Posted October 1, 2010 You might get the broken piece removed with an easy out and not have to rethread it. Link to comment Share on other sites More sharing options...
Chris_Austria Posted October 1, 2010 Author Report Share Posted October 1, 2010 Funny.. doesn't seem to leak even though the screw is missing. I'll let a mechanic try to get the broken piece out next time the car is at service. I'm glad it's possible to remove.. chaning the oil pan is a lot of work I was told.

BodybyFisher Posted October 1, 2010 Report Share Posted October 1, 2010 I am not sure what the proper torque is on those bolts but overtightening them is not recommended. You should check the proper torque, I recall tightening mine, and I think the torque was in inch pounds, and certainly not enough to break a bolt.

Chris_Austria Posted October 2, 2010 Author Report Share Posted October 2, 2010 It's 10nm (89 something.. in lbs?) I tightened them up to 12nm, can't imagine that a screw can break because of this. I've been driving about 50 miles since than, now the car is in my garage and tomorrow I'll see, if the missing screw makes a difference. Link to comment Share on other sites More sharing options...

In this case, overtightening isn't likely to break a bolt, but it could cause you to damage the gasket. If the tightened bolts cause the gasket to get squeezed too hard, it could crack or be pinched in a way that otherwise caused a break. Your missing one is more likely to be missing because of something striking the bottom of the car than from being in too tight. You should probably have it removed and replaced as soon as you can so that there isn't a place on the gasket that doesn't have enough pressure to make a good seal.
