I have since rebuilt the engine with undersized bearings, changed back to a graphite rope seal, etc. When installing everything, I followed the directions exactly, lubricated the seal, etc. Took the car for a 5 mile ride yesterday shake down ride and go into the throttle a bit to make sure the power was there. Came back and had some oil dripping from the back of the pan. Tonight I checked things over, started the car, let it idle and I had pieces of the graphite rear main seal pushing out the back of the pan. My question is, how tough is it to change a rear main seal in the car and is it even worth itI am NOT wanting to yank the engine again third time this year. I am about 2 seconds away from throwing a cover over it and saying F it. Thousands deep, many hours.

At the risk of losing credibility with our readers assuming I had any to begin with, I must admit to never having built an engine before. Ive done general maintenance, bodywork, welding, complete paintjobs, and even rebuilt a couple of automatic transmissions, but Ive never taken an engine apart and put it back togetheruntil now. People Ive revealed this to usually have the same reaction Couldnt you have chosen an easier engine to build than the 4. My response is always the same and I hope I dont sound smug when I say it Building this engine wasnt that hard.

Ive come across a lot of rumors floating around online about mod motor cams being installed as many as 4 degrees advanced or retarded from the factory. Wanting to verify this, I checked my engines cam timing before removing the cylinder heads. We wont document the entire cam timing test process here, as weve done about half a million cam timing articles in the past 5. The mod motors overhead cam arrangement only adds a slight twist to the process in this boilerplate article. Cylinder Head Flow Chart. I brought the stock heads and the new Trick Flow heads to Westech for flow bench testing. The difference is dramatic. There is a lot of potential in these Trick Flow castings. Stock Valve Opening.

The engine fired on the second crank and ran surprisingly well. After fixing the previously mentioned oil leaks from the gallery plugs in the cylinder heads and fixing an unrelated wiring nightmare under the dash, my car felt really strong running on Blue Oval Chips programming for the Mercury Marauder MAF installed in our June 1. However, Trick Flow recommends reprogramming the ECM after installing its Top End Kit, so I spent the better part of a day on Westechs chassis dyno, as Ernie Mena fine tuned the airfuel ratio and timing. Tuning Ford ECMs requires some sort of handheld programmer that goes between the tuning shops laptop and the ECM. Ernie used the SCT X3 Power Flash programmer I bought from Blue Oval Chips. As a result, my car is now making 7. The torque band is much flatter than stock, as well, making about 3. The car feels much more powerful and a lot more fun to drive. Well have some dragstrip numbers to back up these horsepower figures soon. Whered That Power Come FromStock versus Trick Flow Heads. Stock NPI 9. 2 9. Heads. Stock PI 9. PresentHeads.

Trick Flow customers are seeing. While were still breathing through the cars stock intake and tailpipes, we know there is more potential in these heads, especially at higher engine speeds. Were looking at intake combinations and possibly a power adder to see how much more we can wring out of these things. Note in the chart above that the best naturally aspirated combination may be an early non power improved block and Trick Flows 3. If you want more compression, bolt these heads on a four valve block, which comes with flat top pistons and will net a compression ratio of nearly 1.
