When I took my 727 transmission to get rebuilt I also added a Summit deep pan that adds 2 quarts. It shifts great and does not leak anywhere but a small drop every now and then out of the bottom of bellhousing. The car usually gets driven every other week when I am not driving my pickup truck...

Is it possible for a fuel pump to leak oil from the weep hole? I keep chasing a small oil leak on the passenger side of the engine around the fuel pump. It creates a light oil coat on the front of the block and head. I removed the pump last week and made sure the gasket was good and it was...

I will be attempting to fixt the rear main seal leak for a second time this coming week. I took all precautionary methods the first time around to fix it but was not successful. After doing some more research I am finding tips that I did not know before. Like to clean any imperfections on the...

I just finished replacing the oil gasket and pan. Before that the rear main seal. This is the third time I replace the pan and gasket and it leaked again. No leak with just the car idling, but once I get it over 2000 rpm it leaks. I am using the Milodon 4 piece gasket with a summit racing...

Just finished replacing the rear main seal, oil pump, oil pan and gasket. Went for a drive this morning and it was great. The oil pressure was very steady at about 50 psi on the highway and 20 at idle. ....... However, when I went home for lunch I peeked underneath and sadly saw it was...

I just finished installing a new summit racing oil pan and Milodon crush proof gasket on my coronet 318 / 727 transmission. Everything fit great and no leaks so far. But when I got under the car to inspect I heard a rattle from the transmission cover plate. Looking at it closely it seems...

Well….. I may have done a lot of work for no reason at all. I replaced the rear main seal because I was sure it was leaking. Today when I go to install the new oil pan one of the bolts seemed like it was bottoming out before it put pressure on the pan. I grabbed a different one and it fit...

I have been thinking about the Holley Sniper EFI conversion for some time now. Recently I converted my 318 from the original 2 bbl carb to 4bbl 1406 Edelbrock. It runs great now, but I do have to do some tuning from time to time as weather changes. My curiosity is mostly to avoid the tuning...

Not sure it’s the rms leaking yet. In the case that it is. Is it possible to replace it with the engine and trans stick in the car? The car is a 1967 coronet with 318 and 727 torqueflite. Should be the two piece seal. My thought was to drain the engine oil, remove the pan, oil pump and rear...

I am replacing the pinion bearings in my 8 3/4” diff. The sheet I got from dr diff that notes the preload specs is different from the service manual. The service manual is more but I don’t have it with me now to list the actual numbers. Should I go with the dr diff specs or stay true to the...

I am getting ready to reassemble my rear end this weekend. When reinstalling the third member in the case, does the gasket go on dry or should I add some sealant?

Hello everyone. I am getting ready to order some parts from dr. diff to replace the bearings on rear axles and also do a rebuild on the differential. It is a 67 coronet with 8 3/4" (741 housing) open diff and 2.94 gears. On the website it asks me the bearing journal size, 1.8" or 2.0. Anyone...

My engine leaks a few drops of oil under the front side of the intake manifold when I drive on the highway. It’s a 318 with an edelbrock carb and performer intake. I did make sure to only use the gaskets on the side rails and sealant along the front an back. I’m sure I did not add enough...

What fluid does everyone recommend for a 8 3/4 differential? I have been restoring my Coronet for a long time and the only items left to work on are the spring leaf bushings and changing out the differential fluid.

After messing with the transmission for a while I am starting to see positive results with the shifting. The solution was simpler than I thought, I had to adjust the three part kickdown linkage. I also had the incorrect rod that mounts to the carb stud. However, my acceleration from stop is...

At idle in what position should the throttle lever be? I adjusted my kickdown linkage per the service manual but still seem to be having shifting issues. Without linkage hooked up If I start to move the lever to the rear I start to feel resistance when it is about 90 degrees to the...

Happy because I have been driving my car finally. But frustrated with the transmission. The car is a 1967 Coronet with a 318 and 727 automatic transmission. I have spent 15 months working on the car mechanically and it sounds great. Last phase was taking out the transmission to change all...

I finally got around to finish cleaning and resealing the 727 tf on my coronet. I bent the flexplate in the process of rebuilding the engine so I purchased a new one along with a torque converter. I installed it earlier today and it all went ok, mainly because I use a proper transmission...

I recently removed the 727 transmission from my Coronet to clean and redo all seals. If i bring the throttle bracket all the way forward towards the engine. How far back should it travel before I start to feel pressure from it hitting against the rod? Currently mine will travel until its...
