Sump bolts

[jon_r]

My sump has developed a slow weep from it for some reason, so we'll be changing the gasket next weekend. I have a feeling the bolts were done up too tight and its developed the leak after about 2k miles of fairly hard use.

I was going to go and buy a few spare renault bolts but they are expensive and made from cheese. Has anybody swapped these out for something more conventional that aren't prone to rounding off?

they're an m7 thread so tricky to get hold of, but available if you special order. I'd use Cap head (allen) bolts if they were easier to get

You weren't kidding were you!

Any good?

Stainless steel generally has a higher thermal expansion rate than normal steel, so generally stainless bolts arent suited to this sort of application.

I'd just go with standard grade bolts and torque them correctly.

As Chipster says, the OEM ones are perfectly fine for the application, but the ones you have posted there would work, you would need some washers also. but just get some Renault Ones

What a really nice Job

LOL.

I'll get to Renault then. Knowing how tight those two we tried were, I'll order a few...

They are about £1.30 each from memory.

If you get really stuck Jon I can try dig some out from my old engine I think I kept them in the garage as spares
