Hey everyone!
Wanted to get you an update, as today I brought the RV in to have the ignition timing adjusted to spec. Found a really great garage here in Troy NC called Steves Auto Repair. Steve worked with me and is a Ford Certified technition.
My timing was off by 20 DEGREES! D:
Thankfully having it corrected seems to have fixed my lack of power issues!!
The RV is now able to accelerate up hills (albeit slowly, it is 11,000 lbs. Lol) and accelerates from a stop fine now! Overall the engine itself is performing well now, idles fine, good acceleration, quieter, etc.
However...
The overheating issue still remains. The temp on my gauge I installed reads about 200 regularly while driving, and while it doesn't near 220 anymore after the timing adjustment, it can still reach up to 210 under heavier load. Keeping my drives to short jaunts for the time being.
I am considering starting with replacing the themostat. It should be fairly easy and not overly expensive to at the very least rule it out. The coolant circulates and the pump impeller looked fine when I removed it during rebuild. I am wondering if the thermostat isnt quite opening enough. What temperture rating would be recommended for moderate climate? I dont need heat in the cab much I would rather a cooler engine. What is OEM for a '88 Ford 460?
The radiator does not look like it has buildup at least anywhere I can shine a light in.
I will be rechecking fluid levels too for oil, tranny fluid, and coolant. Coolant was just topped off recently though.
Getting so close to having her running right though! *fingers crossed*
