Chevgene,
Have major oil leaks on 28. Will most of these precedures work for the 28 with 4 cyl. in place? Unable to find in 28 forum.No oil pressure. If pump looks ok is there adjustments that can be made.Best way to remove crankshaft pulley and replace.
Thanks

Hi cars,

The source of most leaks on the 1928 engine is the timing gear cover. It is usually installed with the screws overtightened and leave places for the oil to seep through and drop after the engine is shut off. Removal of the cover and reinstalling is the only cure.

If you don't have any oil pressure There are several things you can do to re-establish the pressure. Try priming the pump by opening a connection and with an oilcan force some oil down the lines to the pump. You can remove the distributor and use a drill to power the pump. You may also remove the pan to inspect the pump and prime it. This is also a good chance to insure the pan is secured so you don't have leaks.

The front pulley is removed by use of a puller. It is a press fit on the crankshaft. When finished it is driven on and finished when in contact with the cam gear.

You can also try to add 1,5 to 2 liter extra oil so the oillevel reach the oilpump housing.

Thank's will try.

Hi Ray,
Around timing gear cover large oil leaks car running
or not. Would removing shims on front main help on the 28, if there's any shims left what should the clearence be? Plus installing new gaskets.

In almost every case the oil leak at the front of the 1928 engine is the timing cover. Remove the timing cover and check the return oil passage, straighten the cover, use a new gasket with special emphasis to the bottom 1/4 of the gasket. This is where oil sits and usually where it leaks. Don't over tighten the timing cover screws as this distorts the cover and causes more leaks.

You can check the clearance of the front bearing. To do so you must support the crank while making the measurment. Shoot for .001 - .102 clearance. Use a new gasket to replace the oil pan. You can shape the front and rear gaskets by making them from bulk gasket material and glue them together around a coke or beer can. This will make them much easier to install.

28 slipping out of second gear. Looked under 40 threads. Tried search no luck.

Thanks

Hi Cars
If you need engine amd transmisson gaskets for your 28 Chevy, I have these in stock. These are new reproduction gaskets made by Best Gasket. Please see our website www.marxparts.com for items you may need.

Cars,
Although the postings for oil leaks about the timing cover are correct in frequency and commonality, I had a terrible time with oil leaks at both ends of the oil pan, at the cork gasket. The original gasket has a tendency to “roll-into” the oil pan at the ends, creating a path for leaks. I tried everything to prevent this from happening, but with no success. Finally, I purchased a strip of oversize cork, thicker than the original cork. I placed the cork in a Bridgeport mill, chucked-up an Exact-o blade in a collet, and with the blade aligned in the direction of travel, I was able to cut a flange in the cross-section of the seal. The flange prevented to cork from slipping into the oil pan.
I also followed the typical practice of cleaning the entire gasket mounting surface with solvent, staring fluid and carb cleaner work best. I sprayed the bearing caps with 3M-77 (no over spray) and pre-curve the cork by tie-wrapping it around a small can. I changed the gasket 4 times before trying this approach. I can change a gasket in under an hour, no lift, and minimal space. I’ not bragging, it’s an acquired skill that I wish I didn’t acquire. I can send you drawing if you want, or even a set of flanged seals.

An alternate is to push some carpet tacks into the cork gasket at least three places, two of which are near the ends. The heads of the tacks will hold the corners in place while you position the oil pan. Once you have tightened the oil pan then just remove the tacks. Be sure to pre-form the end gaskets around a beverage can so it already has the arc shape of the end of the oil pan.

After thoroughly degreasing the bearing cap groove I use a very small dab of contact cement, one on each end and one in the middle. It will not move when placing the sump back on.
