1999 V-10 on F-53 chassis
Just got a Rexall Rose Air 3250BSL with 33,000 miles. Do I have anything to worry about or look for? I have read on other forums that the 99 to 01 year V-10 had spark plug issues. So far engine feels smooth and strong to me.
Thanks
Buddie

The spark plug issues are actually the threads in the head for the spark plugs. Some instances the threads have stripped out when trying to change the spark plug. I had a 2000 Rexall Vision. Plugs are supposed to be good for 100K (what they say) but I usually change them before that so they don't rust up in the head. To me it is more of a time thing than a mileage thing. I know some people who have had good luck pouring some type of rust breaker (PB blaster, Wd-40) into the cavity the plug sits in the night before they change the plugs to help loosen it up.

We purchased our 99 Bounder with the V10 on the F53 chassis in June. So far we put about 3500 miles on it and have had no issues. I have read about the plug issues but have not experienced any with my coach.
When I get ready to change the plugs I will more than likely take it to a Ford truck dealer.

If it ain't broke, don't fix (or worry) about it. The early Triton engines had only 4 threads in the spark plug socket. The aluminum heads allowed the steel threaded spark plugs blow out. Ford corrected this issue by now making the plug hole 8 threads deep. I don't know exactly when this change went into effect. If you do blow a plug, a good shop has Heli-Coil inserts that make replacement threaded sockets without having to remove the head. Ford has a repair kit also to fix blown plugs, but I've heard Heli-Coil inserts are better.

Ditto, the early Triton's had 3 threads as I recall. The biggest issue seemed to come from having the plugs removed and replaced cross threaded. I had my plugs replaced when I bought my coach and made sure that particular attention was paid to that issue making sure that the mechanic had the right torque specs and an awareness of the problem. Seemed to go ok.

I have 68,000 on my 99 and no problems. Still running strong. I am the 2nd owner and I had it for 3 years. Put 10,000 miles on it.

Best thing you can do for that ford f-53 chassis is put steer safe on front axle. will keep that chassis from drifting on hwy. then you can steer it with one finger

We had a 2001 Winnebago Adventurer with the Ford chassis. It was the 310 hp version of the V10 with the same heads. I changed the plugs at 96,000 miles. In 12 years and all those miles I didn't have any problem removing or reinstalling the plugs.
It's best to use an old sparkplug boot or something similar to hold the plug so you can thread it in by hand. It should thread in smoothly until you feel it stop at the end of the threads. Then you can torque it to the proper value. Proper torque is just as important as not cross threading. Over torqueing will strip out the threads in the head.
I believe the proper torque in 168 IN/LBS. That's only 14 Ft/lbs. It doesn't seem like much, but if you just give the socket a good twist you're going to over tighten them and possibly strip them out.

Right after we bought our "New to Us" MH, (65k miles) I replaced the plugs and boots to specifically mitigate this issue. I made sure the new plugs were the nickle plated ones (base is a silver color) as opposed to the plain steel ones (base is a black color)
The correct amount of anti sieze and correctly torqued the plugs (160 inch lbs) (even bought a new torque wrench specifically for the job.
When we removed the old plugs, there didn't seem to be any problems, I suspect they were never removed before.
From reading the threads on the Ford group, I'm led to believe that this problem is vary rare, and when investigated, can be attributed to plain steel plugs that were not torqued correctly.

I had a 99 F-53. At about 45,000 miles I replaced the plugs with the newer "improved" ones. A little anti-seize on the threads and torqued to spec. It had 75,000 on it when I traded it in and never had a spark plug issue. When a plug starts to come loose it will sound like an exhaust manifold leak. If you hear that sound check it out ASAP.
