Been leaking for the past 100 hours(I have been tightening the 3 right bolts on a regular basis). Oil level never really moves just light oil all on and around the motor. I took out 3 of the bolts the other day and locktighted them back in but it still leaks.

Do I need to fix this thing now, or can I just keep running it like it is? I am just sick of wrenching on it.

Cause they arnt loose.

Just go ahead and change the case gasket!!Get with Robert at EVT and get him to hook you up

I wouldn't worry about it as long as it's not too bad. This is a common problem with all big bloc vangaurd engines. They all do it. One option for you would be to replace your bolts with ARP studs provided by EVT along with a new cover gaset. Many people have done this and seems to be the best fix.

I wouldnt worry about it until you are loosing a noticable (on the dipstick) amount of oil.

I had some good success with an EVT case gasket & studs in my block.... went about 200 hrs with no leaks until I threw a rod through the side of that block.

Since the rebuild I've tore this mofo apart 3 more times due to case gasket failures and a cracked sump.

The last time I drilled & tapped my block for 10mm, and drilled out the sump bolt holes to barely accept 10mm socket head bolts with a real tight fit so that every one essentially acts as a dowel pin as well. Used a stock gasket with loctite anaerobic sealant. Cleaned all bolt holes & bolts real well with carb cleaner, used red loctite thread locker on the threads as well as silicone on the section of bolt that goes through the sump.... then torqued that mofo to 25 ft/lbs and put position indicator marks on all bolt heads with a paint marker. lol

















then I just noticed the other day I had a small leak around the oil galley

every motor is different.........with a stage 1 i had good sucess with stock bolts and red loc but stage 2 broke every bolt i put in her and the gasket would last 10 min.

If you are leaking don't mess with it till it blows............just keep some oil with ya to make it to the ramp.

later

My PD 36 did it at 75 hrs!!Replaced it with a EVT gasket,The guy is still running it and no leaks Fix the damn oil leak!!Don't run around with oil leaking!!Damn

just run it till it gets bad.

We are on our final idea about this leaky gasket shit!! If this dont work then its just meant to be lol

extra dial pins
gasket with anaerobic sealant
studs red lock tightedand, nuts also red locktight
running dual vented valve covers!!


If this mofo leaks hoyt said he uits lol!!

We are having great luck now with 10mm ARP bolts and our gasket. Cover can not move. Puting about 25-28 ftlbs on the torque. When the bolts start to loosen the cover can move. When the cover moves it chews up the gasket and you have a leak. When the cover moves too much and the cover has more torque applied to it eventually something will give when the bolts won't. If the bolts give cover cracks, if the bolts up top hold then it splits the block. If both go well double trouble.

Mine started leakin last trip out. 68 hours. Its not bad enough now to replace it yet, But its annoyinh to see an oil slick on the side the block.

Yea, mine leaks a little as well, but aint going to mess with till it gets bad enough to actually change!

Mine started leakin at around 110 hrs.. Brought it to the local Briggs shop and they fixed it.. And under warranty

mine went over 200 hours without leaking at all- go figure.

I remember when the mo yore Harley leaked ... the cooler it was !!!!

I talked to the guy where I bought my motor from the other day. It is covered under warranty, he says Briggs has changed the gasket.

He sees an assortment of results from leaks like me at 75 hrs to some with 800 hours and no leaks. I have had 3 or 4 hard impacts, but so does everybody else. As long as its not pouring out, I guess it doesn't matter. I guess I'll wait a little while and bring it in whne I see some down time coming.

Mine started leaking at 80 hours as well, sent it to Franklin small engines....fixed at no cost still under warranty.
