Question about Ford F-100

1 Answer

No compression (except #4 @140 lbs), but cranking power.(352 v-8)

The truck wouldn't fire all of a sudden. Had normally low compression for an aged engine (1966 ford f-100), then no compression except number 4. Removed water pump and chain cover, found a WAY loose timing chain. I want to know why. I also found the front cam bearing basically missing, if that helps. I also want to know how to remedy the loose chain issue. Why it happened, and how to fix it without removing the intake manifold.

    is this a 351 cu in engine? I think your engine has jumped time, and if you have a bad camshaft bearing, you will not be able to repair it without removing the intake manifold, and the camshaft, let me know

Compression


The head on the motor you bought is bad; or the head gasket is leaking; or the rings in the 2 center pistons are bad. 30 lbs is far too low of a compression, and 5 lbs is garbage. They should be closer to 80 or 90 psi and not have more that 5% variance between the cylinders.
The first thing you will have to do is pull the head off and check it. Or you can take it back to the salvage yard you got it from, show them the results from the compression test and either get another motor, or have them refund your money.

Reasons for cylinder misfires


Ford coil on plug systems are multi strike ignition (spark) under 1300 rpm then go to single strike a single cylinder misfire can be created by several things . #1 Test engine compression on a cranking engine compression it should be around 150 lbs but if gauge reads different COMPARE to other cylinders that work fine #2 check engine running compression this will be around 120 lbs then rev over 2000 rpm and check pressure drop again COMPARE to other cylinders that work fine. any drop would indicate valve train problems. #3 All internal engine is fine then external problems are present vacuum leaks and or fuel injection volume is low.

I have a 02 Saturn SL 1.9 SOHC I have changed 1 coil pack & spark plugs but it still misses bad & check engine light flashes


check compression ..a difference of 15 lbs compression from cyl to cyl will cause in balance. if ok check crank sensor, supplies signal for coil to fire

Sound like you could of solved a misfire hows the cranking does it sound smooth example ta-ta-ta-tataaa-ta-ta-ta-taaa-ta, that would be a low compression cylinder, recheck the firing order

# 4 cylinder 30 lbs compression


it indicates a sticking valve or lifter. you will have to do a leak down test to rule out the piston rings for that cylinder. most engines should have 140 to 160 cranking compression. a low compression on one cylinder indicates a bad exhaust valve. have a good day !!

1999 chevy suburban 5.7 L. vortec. Can a bad camshaft sensor cause a no start? rebuilt engine, fuel pressure 60 LBS.,spark at all the plugs, compression 140 lbs, timing is dead on.


i do believe it will not start with out it if you can hook up a scan tool to it crank the engine and look at rpms while cranking should read about two hundred forty rpms thats what fires the injectors the cam sensor tells the computer what cylinder is ready to fire next also scanner will set the cam timming.

Can,t get truck to fire ,just put fuel pump in . checked fuses,made sure fuel is pumping


the truck has to have the basics . Spark fuel and compression in that order. Remove a plug wire from a plug either remove the plug or install a different one in the end on the wire and crank the engine with the plug laying on engine ground in good view and see if there's spark. Being you did'nt mention what motor is in the truck, desiel. 10 cylinder gas 8 cylinder gas 6 cylinder gas 4 cylinder gas I can only guess at what kind of engine were working on. The gas engines have spark plugs as the desiel has glow plug heating system and direct fuel injection. Silveradoo is a trim level and theres 1/2 ton 3/4 ton 1 ton and 1 1/2 ton versions. They all have fuel pumps and if they have more than on tank or a desiel they can have more than one. The gas engine v8 has troble with the ingtion and the module is the most likly for the cause of no spark but the mileage wasn't stated so I have no idea where to start. if it still is'nt getting fuel with the new fuel pump it's still possible that is'nt running or if it is its wired backwards and is pumping backwards. If the fuel pressure checks OK (above 50 lbs. that part shold work. Below 45 lbs they might run but they won't start. Compression has to be good 100 lbs or more on any engine. most chevy engines are much more in good shape.150 or even as much as 220. low compression and it was running OK the last time it ran sort of says the timing chain skipped as the compression normally does'nt go away quickly. The exception to this is overheating and racecar type blowups. some engines after overheating will have little or no compression and if started with added fuel and revved up they can unstick rings and or valves. and go back to normal. the reason for the overheating needs to be found as this happens again the motor might not come back to life.
