Repair Mistakes & Blunders
Repair Mistakes & Blunders

My father-in-law is a retired master mechanic who ran his own shop for several years. One of his frequent customers was a kindly older gentleman who drove a 1983 AMC Concord. The car had a chronic problem of running too hot, especially at highway speeds. My father-in-law attacked the issue one visit after another until he replaced nearly every suspect part – hoses, water pump, belt, radiator, sending unit, thermostat, you name it! Still, the problem persisted.

When the car’s owner passed away, the car was left to my father-in-law as thanks for all the work. Now convinced the system was somehow clogged, he removed the head on the inline 6-cylinder 258cid engine, had it professionally cleaned, and reinstalled it (with new gaskets, bolts, etc., thanks to RockAuto). Nothing. Shortly after, he made the 7-hour trip to visit us, which is when he complained to me about the problem. I suggested we both look it over.

We stared at the engine as he told me all the work he did. Then I asked him to start it. No sooner did it turnover, I told him to shut it off. The fan was blowing the wrong direction! We quickly determined flipping it would make no difference because of the blade pitch. After a little research on RockAuto, we learned AMC sold the same engine with optional belt drives. The standard V-belt configuration turned the fan clockwise, while the serpentine belt configuration turned the fan counterclockwise. We replaced the fan and the old Concord has run at the correct temperature ever since.

A Surprisingly Simple Repair
Tom's Story

I was raised believing a leaky crankshaft rear main seal was a serious, expensive problem. Some vehicles do need to have the transmission removed, but for many of the most popular old rear wheel drive cars and trucks, rear crankshaft seal replacement is surprisingly simple. DIYers who feel comfortable replacing an oil pan gasket have already done 90% of the work needed to replace the rear main seal.

I recently decided it was a good time to replace the leaky oil pan gasket on the 360 in my 1979 Chrysler 300 (Cordoba). The repair manual's detailed instructions were exceptionally accurate. The oil pan came right off once I stopped trying to wrestle it loose and slightly jacked up the front of the engine like the manual said to.

With the oil pan removed, accessing the crankshaft rear main seal required simply removing four bolts; two that attached the oil pump to the rear main bearing cap and then the two bolts that held on the bearing cap.

Rear main seal

The rear main seal comes in two pieces that form a circle around the crankshaft. The new orange colored seals in my photo may look like pieces of soft rubber. They actually have metal cores and are surprisingly heavy. Follow your own engine's repair manual instructions (found under "Literature" at, but here are some general tips:

The seal attached to the bearing cap can easily be pulled out of its metal groove and the new seal inserted. Usually the thickest or only "lip" on the seal faces towards the engine.

The upper seal must be pulled out of its channel over the top of the crankshaft. My 360 still had its original "rope" type seal which resembles tightly braided rope. Rope seals are more likely to pull apart than modern seals are. This rope seal actually came out easily. I pushed one end of the seal in as far as possible with a dowel rod that I tapped with a hammer. I then pulled on the other end of the seal with pliers until it popped out. Seal Remover tools are available to assist with any ornery seals.

The new upper seal simply slides into its channel; being careful to make sure the correct side (lip) is facing the engine. Lubricate the new seal so that it slides in easier and is not bone dry when the crankshaft turns for the first time.

The seal manufacturer included a strip of plastic to use like a shoehorn to prevent the new seal from scraping against the sharp metal at the channel mouth. You could make your own tool out of an old credit card. The plastic shoehorn is most useful on engines that have a U-shaped seal that slides over a metal ridge than runs the length of the channel. The shoehorn prevents the seal from scrapping against the beginning of that metal ridge.

As shown in the photo, the upper and lower seals are often slightly offset so that the joints where the seals touch are not exactly lined up with the joint between the bearing cap and engine block. Sometimes it is recommended to put something like a drop of RTV silicone on the seal's ends to help join the upper and lower seals. I did not do that because neither my service manual nor the seal's instructions called for it. I also thought silicone probably would not stick to the seal ends because they were now covered with a film of lubricant.

Be sure to follow the engine manufacturer's torque specification for tightening the bearing cap's bolts. Getting rid of messy oil drips is a great way to roll back the years!

Kristoffer's 1986 Chevrolet M1009 Blazer
Kristoffer's Chevrolet M1009 Blazer

This truck is a military-surplus Chevrolet M1009 I purchased from the National Guard. It has air lockers in both axles, 33" mud tires, and is my daily driver. It spends at least 15 nights a year deep in the back country off-road camping all over Utah, Nevada, and California.

I swapped in a SM465 manual transmission and a NP205 transfer case along with an auxiliary gear splitter, for a total of 16 forward speeds and 4 reverse gears. All the parts for the transmission swap (clutch, flywheel, hydraulics, park brake cables, etc.) are RockAuto parts.

On my last off road trip we cracked the original radiator and broke the worn-out factory steering. I have since repaired the cooling system (water pump, radiator, all hoses and fittings) and entire front axle (bearings, seals, ball joints, tie rods) with parts from RockAuto again.

At this point I have been wheeling hard and doing regular maintenance with RockAuto parts since 2017, and the only parts I have ever broken are 30+ year old worn-out factory components. I trust parts from RockAuto to get me and my passengers into and out of the back country safely and will continue to do so in the future.

Thanks RockAuto!
