You'll need to remove radiator, shrould, belts, distributor (make sure you mark the position of the distributor and rotor after you line up the crankshaft pulley with the TDC mark on the timing cover), water pump, the harmonic balancer, (you'll a harmonic balancer puller). fuel pump, if mounted on the timing cover. Remove the first 3 or 4 of the oil pan bolts, remove the timing cover. It may help to place a screwdriver in between the the oil pan and engine, to lower the pan slightly to get the cover off. Remove the timing chain and gears, and reinstall, Replace the from seal. Make sure to use some silicone sealer at the block/pan/cover mating surface.

1969 with 351 Windsor stock engine. Once it reaches 1,500 rpms why do the tach & engine jump up and down?


If this is a points type ignition, check for excess play side to side in the distributor shaft, and also for timing chain slack--easily tested by removing dist. cap and rotating engine back and forth with wrench on crank pulley bolt. If rotor doesn't move immediately as crank turns you have loose timing chain.

It has a 351 Windsor motor in it. I has a terrible knocking sound. We replaced the main bearing and timing chain. What could it be?


How were the rod bearings? I always check them whenever replacing the main bearings. Why did you only say "main bearing"? There are always more than one.

could also be part of the fuel pump dropping do into the oil pan is now hitting the crank, but you checked the oil pan for "bits and pieces" when you took it off to change the main bearing - right?

1983 Ford F-250 w/351 cid engine has jumped time. I will start, but backfires severely. What is estimated cost of repair?


Timing chain set $25, timing cover gasket set $15, 5qts of oil and filter $20, one gallon of antifreeze $8 take about three hours to do, about $80 an hour for labor if you take it to someone. Think about replacing waterpump too, be another $25.

I have a 1965 food falcon with a mustang 302 (1978 ) v8. how do i know if it is a windsor or not?


Well there is a 302 cleveland, they are mainly an Australian engine. Identifying one is much like telling the difference between a 351 windsor and a 351 cleveland. Based on the fact that it's from Ford's 335 engine family. 8 cap screws to hold on the valve covers, the block is longer do to the timing chain housing being integrated. The fuel pump bolts are mounted vertically, and the exhaust bolt holes are diagonal. Also, a big difference between an american 302 and an aussie 302 cleveland, is the connecting rods for the cleveland are 6.000''. Where the american 302 connecting rod length is 5.090". Also, referring to a 302 as a windsor is incorrect, it's block families name is the 90 degree v8. The only engine in that family that is properly named the windsor, is the 351 windsor. The 90 degree family also includes the 302 boss. The boss has cleveland style heads, and the block has screw in freeze plugs.
