Is this what i need? Stripped oil sump plate bolt

[Tysoe]

Hi guys,

Did an oil change at the weekend on my newly acquired van and found that one of the Oil sump plate bolts was loose and wouldn't tighten (just keeps turning) I guess the thread is stripped in the block. After a quick search found others with same problem and someone suggested an Oversized stud, found this on JK

Is this what i need? Screw this into the stripped hole and tighten with a nut as opposed to using a bolt?

Just to clarify this is one of the sump plate bolts, and not one of the 2 studs that you use nuts on.

Hope that makes sense

I believe that is just a generic oversize stud for when a thread is stripped anywhere in the case. to fit it you would need to drill and then tap the case to the size of the oversize thread. just bolting in wouldn't work as although your thread is stripped it still wont be as big as the oversize stud.

having said all that, not sure which thread/bolt you are talking about, info on vehicle, engine and age would be helpful or even a pic as there are major differences between engines

Sorry i laways forget to put details on

It's on a 1981 CT1600 engine T25. As far as i know same parts as the T2 and T1 engines in relation to the sump plate etc.

The bolt in question is one of the 6(?) nuts/ bolts that hold the sump plate on. 2 of which are nuts which screw onto a stud and the other 4 are bolts that screw into the case.

What is involved in drilling and tapping the case? The drilling bit speaks for itself but what do you mean by tapping the case?

Thanks for your help. Looks like it's gonna be another oily weekend!

tapping= cut new threads, with a tap and die set. drill out to a larger size hole then cut the threads for a new size bolt. does it leak with just the one bolt not happening? the other 5 may have enough to hold it I think thats why they moved away from the single central bolt on the CU at a guess.
