Any opinions on the Racing Beat oil pan baffle plate? Good/bad/indifferent?



Not sure if this has been discussed before - the search function was being uncooperative for me.

It does its job, but they have a tendency to leak.

I have had success by making my own studs to replace the too short oil pan bolts and then using two gaskets and RTV.

scathcart Is right...you will need larger Bolts. I have put In the stock Bolts through my Oil Pan, RB Baffle Plate and 2 Gaskets and It Is tight! ss ones can be found at Home Depot/Home Hardware.

pfft... bolts... Studs are so much nicer to use.



There might even be a kit that fits, though I haven't tried it.

You might be able to order '71-'75 (or was it up to '78?) oil pan bolts from Mazda. They are longer and have lockwashers. Older oil pans had extra cover pieces that fit between the bolts and the pan to help prevent leaks. They did work, but Mazda found it more cost effective to simply go with single peice short bolts and a flat gasket surface on the oil pans.



Just make sure that if you get an old (NOS) set of bolts, that you make sure they won't bottom out before becoming tight. I know a guy who wasn't paying attention and snapped an oil pan bolt. He had to drill it out and tap for the next common size up which was an 8mm x 1.25. Regular oil pan bolts are 6mm x 1.0 (not sure of the length).

I had installed one in my reman, so far its been great no oil leaks (about 1k miles). Although I am sure it is to soon to tell. I used the stock bolts with 2 gaskets and alot of RTV. I only had problems with one bolt not wanting to tigten.....
