Thank you all for your feedback. Sounds like I should do a little more work on this before I change the motor. Its just such a bear working on it in the vehicle. It overheated when a thermastate failed and I didnt notice the guage until it started loosing power.. I shut it down and let it cool while it was foaming out the overflow canisted. At that point I believe the radiater failed as the trans fluid and coolant were mixed together. So after a few hours of flushing it ( no thermastate ) and cool down I drove about 100 miles to get home.
seemed ok but noisey. I assume it was in fail safe mode. skipping forward I replaced the radiater flushed the trans twice, new filter and ran ok but ten miles later it started ticking. Took out the fresh 10-40 and put straight 30 in and still ticked 05-20 in effort to see if it was a oil problem or a clearence problem still ticking so I figure it is a clearance problem.
After some research, I pulled the pan to ck the pickup on pump, was clean. No parts in pan. Then I pulled the passanger valve cover (5 Hours ) all looks good no parts laying on head chain tight, cam follower is intact, so Im thinking something is warn maybe a cam allowing more clearance than should be. But at this point it sure would be alot easier to work on it out of the vehicle and that is why I was thinking of swaping the motor for another. I actually bought a doner vehicle today.
But maybe some further work is a good idea. When I checked into the cam phasers, It was unclear to me it this 98 5.4 actually has them because it doesnt look the same as what I see on the internet What I am unfamiliar with is the duel cams and dealing with the timing if I got to that. Im just afraid of this which was part of the decision to swap it out.
Maybe what I should do is yank the motor and change cam phasers, ch all exhaust studs put a throttle position sensor in it see what happens. You guys have been very helpfull thank you
