I've the same problem. I got a 1973 F100 with orange covers and air filter. According to the VIN, it should have a 6cil engine.... it is a V8.
it will make it sound like a ford
First of all are you talking about the valve covers or the valves them selves because if your talking about the valve covers then over tightening them will break the gasket in between the valve covers and yes the engine will smoke and if your talking about your valves themselves then the only thing that will happen is the intake valve will let oil into the cylinder and will foul out the spark plugs
Removing the valve covers on an E series Ford van can be a challange. I have read many accounts where people are suggesting raising the body off the frame or removing the engine. Yes, these are effective ways to access the covers but easier said than done. The fastest way that I found is to support the engine with a jack and remove the motor mounts on both sides. This will allow the engine to drop down a good inch or more and will allow you to remove the covers with a little twisting and turning. A tip to make it easier is to remove the bolts and groumets from the cover as they tend to hook on things as you pull the covers, also you have to pull the covers out the front of the engine as the cam gear is in the way. Good luck, jims grey garage.
the torque specs for valve covers on the 3.0 SOHC is 7ft/lb make sure to clean the oil and old gasket material off well and put the RTV in the corners. take great care not to roll the gasket on the rear valve cover!
take the bolts out that hold the covers to the engine and pull the covers off then scrape the old gaskets off the valve covers real good and make sure where the gaskets contact the heads of the engine that it is also clean, get some permetex and put some on the valve covers where the gasket goes in to hold them in place when you lay the new gasket in place and let it dry for about 10 minutes and then your ready to put the covers back on and tighten the bolts down to about 10 to 15 ft. lbs.
If it's an overhead valve engine that has the cam under the intake and not in the heads then you need to remove the intake manifold and the valve covers. Then remove the rocker arms and push rods. Use a valve lifter removal tool to make this job easier. The parts stores like Autozone usually have a loaner you can use for that. I do recommend using a Rust/Varnish remover type spray to soak down the lifter bores BEFORE attempting to remove the lifters to make it much easier. Good Luck!
According to Gates ( they make timing belts etc. ) the 2.3 liter - 4 cylinder engine in a 1989 Ford Ranger is NOT an interference engine so there should be no valve damage
adjust your lifters and valves under your valve covers to spec. look in your heyens manuel.
see if you can run them along the valve covers make sure you tie them off so they do not interfear with anything
that my friend is the tube that goes from the exhaust manifold to the egr valve make...
yes, from either jegs or summitt etc. made by edelbrock, and one by holley
sounds like bad valve guides, and/or rings If engine runs smooth when hot? I don't think it's the guides I would check the valve seals. also need to pull valve covers to make sure oil return holes are open in the heads.
