I don't mean to split hairs but what they have is suction; vacuum is created when suction draws against restriction.
Since it sounds like you have access to a hand vacuum pump I would check the system from the solenoid (on the right fender well near the battery) down to the hubs. There...
I believe that on the trucks that came with dual alternators they were controlled by the PCM; not sure how you would manage that. If you were charging a separate battery from the existing system in the truck I guess there would not be a problem but if you are going to feed both alts to the...
Hey TBar,
The 99s and early 2000s had round ears on the torque converter clutch plate (about 3/8" radius if memory serves) where it goes into the grooves of the converter housing. The later 2000s on had square ears (well, OK, radiused the same as the inside circle of the converter housing but...
Well...... Since the system does not operate when the ambient temp is above 40* I doubt that yours has been used in quite a while. Working on that assumption, I'd guess that your leakage has nothing to do with the solenoid being plugged in or not. When was the last time that your startup temp...
It is probably going out the back of the valley and down thru the bell housing while you are driving. I'd bet that you would see it when you park on wet pavement.
Has anyone ever had that system work? I have never heard of it working and if it were me I'd put a pipe plug in the hole.
I can't remember if you said that you have tested the compression? Did you look at the UVC harness connection to the valve cover gasket?
I have not heard of '99+ pitting the filter housing all the way thru like the '94-'97s. IMO it happens when there is a layer of sediment in the bottom and some water accumulates in the housing. Since the water is sitting in the sediment it stays in one spot and does not get drained by the...
I have a FASS on my brand "D" truck and went to a Fleetguard water separator/filter. It's my understanding that it is the best water filtration available but I don't have the numbers in front of me.
I really like the system. I've seen 2 on Fords; one that supplied fuel to the stock lift...
You know, I almost asked about your batteries; but you didn't mention any cranking problems.
It is my understanding that Optimas do not like charging voltage over 14 and I don;t think that the voltage is held at 14. I've known of a few Dodges that had this issue and their charging voltage is...
The UVC harnesses are usually fairly durable on the '99 and up but there is a posibility that if a gp wire was in the wrong position that it could be rubbed by a pushrod or chafe itself against something.
The tool dealers have Amp clamps but usually not the best price. Seems to me that I...
There are some codes that indicate Glow Plug system problems but I haven't experienced them. I'd suspect that if it did not work at all it might throw a code. That controller has one half and connector per bank and the gp wires are run to the controller individually (unlike Fed spec pickups...
If you watch the Oil Temp PID get it at least to about 180*F (better still make it 200*) so that it won't cool off during the test. You can run the engine at a fast idle (2000 RPM should do it) to warm the oil.
To get the most from the test observe how the engine reacts to each cylinder...
WOW! Great article!
There is no seal on the rod where it sticks out of the pedestal, it is normal to see space all the way around it. There is actually a drain back to the crankcase just inside the hole that is supposed to handle any minor leakage past the piston. And since the oil...
