 |
|
Howdy - While adjusting the carb today on Felix, my '67 Beetle, I noticed a smidge of oil coming up from the bolts around the fuel pump on my stock 1500sp.
Anyone have any ideas why it would leak through the bolt points? The bolts are appropriately tightened..

Sometimes its just a matter of replacing gaskets.
Sometimes when you take off the nuts and pump
you will find the studs are actually loose, not tight themselves.
You can clean threads best you can with rag and use
a thread sealant. Like locktite but there is a tube that
is designed to seal threads. Just make sure enough thread
for nuts if studs go in deeper. Looking at photo studs can
go in a few threads deeper to tighten them if loose. One
and half threads past nut is what is required.
Use new gaskets and only put a little sealant on gasket
that is on bottom against block. None on top gasket its
not needed.
HOpe that helps. |

Thanks, Everett. Standard washers or wavy washers there for a '67? I'll get them ordered up and put in place too.

This is sort of a different topic but it looks like you don't have a washer under that nut either.
I don't know if that will affect the sealing but there should be a washer there. |

Lockwasher/wavy washers.
Don't overtighten, you break that plastic flange (which might break anyway when you try to remove it). Just saying to warn: you could make a little problem into a bigger one here if the plastic flange breaks when you try to remove it. Maybe someone here knows if there's better or worse chance of breakage there if flange removal is tried with the engine hot.
Anyway: remove the pushrod before removing the plastic flange, and note which way it is pointing.
Has anyone ever tried the nuts with rubber seals for an oil seepage issue like this?

You could try using Dowty washers here (available from hydraulics places). I've used them with success where studs may be weepy...
