Oil leaks

Put new pushrod tubes in but they still leak very slightly I used the ones from Scat .Any help her is apreciated . Then when I drove the car, yes I drove it what a blast finaly she is on the road .But for some reason it pushes oil up the dip stick tube ???? WHY ??? I do not think it is overfilled it is up to the first line on the dipstick cold .It does have the extra sump . So has anyone ever had this problem .But i did drive her and what a joy it was!!!It runs and drive good!!

Oil out the dip stick is excessive crank case pressure, do a search here for methods to resolve this. i.e breather box vented to the carb(s) and case. ~Alan

Alas, poor oil leaks! I know them well!

Pete, here's a picture of the (not)pattented Alan Merklin oil breather system, as implemented in my car. Look in front of the shroud with the two little filter thingies on it. One hose to each valve cover, one to each carb, and two filters. I am still debating replacing one filter with a hose to the oil filler neck.

COOL LOOK!!

Yes, and those are dual espresso machines back there, too.

You can't see the special milk steamers, as they're on the back of the machines, but he can do Lattes, too......

A Latte will be great in the rain at Carlisle!

I think the "COOL LOOK!" comment was aimed at Pete's Envemo.

However, I have since painted the "espresso machine" covers, and added some brass fittings to repalce the white plastic ones. The coffee tastes much better now, particularly without the extra oil infusion.

So i had brain fade late nights .I hooked the breather from the oil cap to the fitting on the dog house which was pushing air into the crank case causing oilo to come out of the dipstick Now ol i got to do is get the pushrod tubes to stop leaking.

I would have put some hi-temp RTV sealer on the tubes when I installed them (after cleaning head/case sealing surfaces).

And here's a picture of Lane's newly "Brassed-out" aircooled Speedster engine, sitting atop its' garage display podium:

It has the newly developed, extra tall, central cooling tower, dual "Bigga-Huffa-extremio" carburation, the easy-access oil filter (The Superleggato-Filteroneo-Maxima), and the much sought after, "Shifter para Dos Capitanis", able to be instantly adapted for left hand or right hand drive Speedsters (a distinct advantage for those with both British and Italian drivers swapping off during the race!)

That Lane Andersonio......Always one step ahead of the sheep herd!

That looks like a mini moonshine still they have real big ones here in Robinsville all out of brass .Makes good stuff

Pete, where do the tubes leak from, the seals on either end or the o-ring seal in the tubes themselves?

Greg, I don't use sealer on the heads or case, just new white seals every time they get changed, and CLEAN surfaces.

They are leaking at the ends into the heads.I took them back out cleaned all surfaces .I do not and will not use silicone near any internal engine parts .So i coated them with a slight coat of aviation pematex and they seem to be OK.

When installing pushrod tubes, I always stick the handle end of a 3/8" ratchet into the tube and flex the bellows just a bit to draw out the bellows, effectively making it longer.

Then, when you install them they seat better and seem to seal better.

But the permatex on them is always a good idea....
