my 225 v6 leaks oil, is it a common problem?

I'm wondering if my oil leak is common to the Dauntless. Oil puddles on water pump indentations right near the distributor hole. P.o. said the dist. shaft flange needed a new gasket. New H.E.I I installed has gasket ,plus o-ring and I sealed the bolt threads on the dist. clamp. Still a leak. Looks like the front of the intake manifold is the likely source. Are either of these locations a common area to leak. Just wondering if factory gaskets will take care of it. All in all, if this is the extent of my used motors problems, $400 was a good deal.

 

Yes yes yes! The intake manifold front/back rubber seals are notorious for oil seepage. If you get down close and peek at the seal, you might notice a bit of the seal dislocated outward. Leaks from the intake are usually a bear to track down because the leaking oil travels down and disguises itself as a leak from elsewhere.

There has been MUCH discussion on how to prevent these types of leaks. Just do a search on inake maniflold seals and read up on RTV vs. rubber seals. I'm a believer in using a dab of RTV sealant in the corners where the manifold meets the heads (on top of the stock rubber seals).
HTH!

how bad is it? might just top off every so many days.

 

Mine has the same disease. Both front and back.

 

Ditto here. I had to pull my manifold off several times before I got it to seal correctly. The rubber seals on the front and back like to roll in or out unless you set the manifold down juuuuussssst right. And, like Alan said, use some RTV in the corners.

 

intake seals

Try this guys when installing the rubber end seals on the intake---make sure block surface is clean, use laquer thinner, carb cleaner ect.. put a thin layer of rtv on block all the way across and a little extra in the corners , install seals, apply another thin layer to top of seals with a little extra in corners again , set intake on block an put bolts in finger tight only and let sit for an hour, this will allow the seals to bond to the intake and block so that they wont squirt out when you tork down the intake, if you still have trouble and want the seal permanent , use permatex intead of rtv following the same procedure, I have been using this proceduere on engines for years with excellent results. good luck

 

thanks

 

Go the way ssolds was telling you on this ,permatex and exxtra clean. I run a 225 myself and this works,a little time consuming but let it set like he was telling you then tighten up . Aside from a rare case these engines do seal up, good luck , I know it will work for you.
