Another great video. John, I have a 73 MGB and just bought a 72 project car for my son. We have it running and use your "youtubes" all the time. Thanks for your great contributions!!!!!
The point about leaks via the oil pressure tube is that at idle, when looking under the hood, it may NOT leak. While at the road at higher speeds and oil pressure it does, but the oil then leaves less traces. That's why it took me more time to find.
I never use silicone based sealant where oil can touch it. Oil eventually turns silicone into a stringy-goo. I use Permatex #2 for both sides of the oil pan gasket, side cover gaskets, filter head, and where the valve cover gasket meets the valve cover. Between the valve cover and the head, I use a liberal coating of anti-seize compound (seals and comes off easily for valve adjustment). I use silicone only around the cooling system. I can proudly say my B has never leaked.
Great video..... I actually got the EVC leak problem. I am finally realizing the "big connection" and am going to change the filters/charcoal in the absorption canisters as smoke tends to come out of the Oil Filler cap rather than having a vacuum.
Nice one John - nothing like experience. My breather gasket is rubber and leaking like bug...y. I have just ordered a pair of thin cork ones. Keep up the good work. Many thanks David
There is no mention on the danger of overtighening the bolt holding the oilfilter pedestal to the block. Some people on MGE state the washer on this bolt leaks if not tightened enough, but once tightened the rubber ring between pedestal and block will start to leak on the edge. Personnaly I just retighened this bolt with a 1/2" socket drive and a metric hexagonal socket this week and removed the leak on this edge this way, but I only checked this joint during a heating cycle of over 45 minutes on raised idle. I wonder about any other experiences, there are no newer posts from JT to be found on this subject. Nor on transmission or gearbox/OD leaks for that matter, something that suddenly came up on my B after over 40 years of lossfree driving :-(
Yes, one other source he didn't mention is the rear main seal around the crankshaft. That'll leak and drip down into the bellhousing, where it end up on the exhaust pipe brace. The oil runs along the brace until it contacts the exhaust pipe and burns. Hopefully John will do transmission oil leaks, which is what my MGB is suffering from....
Hi John. I'm new to MGB's (1979, no emissions). Great videos - Thank You! You mention cork for the front. Do you recommend cork for the rear too? Best Regards - Kevin

Excellent videos John. Thanks for sharing!

Could that leak be from the SU single carburetor or could it be the carburetor oil.I smell oil burning and have changed all the gaskets. help lol
Is that a 1275? My midget is maybe leaking around the filter housing but it also has the thick side cover gasket. Trying to find out where it could be
Can you make a list of all the oils on a 1979 mgb
Great videos. Yer a life saver. How about a hydraulic clutch video. Mine is new but just quit working on my '78 MGB. Chow
