Question about Taylor Wires

[stearn]

Last year I had an engine miss, I took it in under warranty for repair. Having read about this problem here I asked if I should have the vent to keep the engine cool. I was told I had a couple wires broken not burnt, so not necessary . Well a year later and 5000 miles, I have the same engine miss, now out of factory warranty. I do have an extended warranty, but I would rather do a permanent fix.
I have read about the Taylor wires and am wondering if they are holding up or is the air dam something that needs to be installed. I have the Adventurer 38R with 19,000 miles. The original wires were replaced at 14000 miles.
I have read several threads but did not see anything about the longevity of the Taylor installation. I know I will hear from the folks that know, and have the experiance. I am very thankful finding this forum, cause it is full of valulable information!

Taylor wires or any other manufacturers wires will NOT fix a bad air flow problem. Taylor 409's are best in my book.. The Extremes (409's with dual layer boots) are even better. I suspect you need the vent kit...

The bad air problem is a "coach builder" problem that Workhorse provided a fix for.

I sure hope someone on this forum gives you a answer stearn. I’m in the same situation as you having had two wires replaced under warrantee a couple years ago near the 9000 mile area. I tried very hard to get a miss again before my warrantee ran out but even Colorado mountain driving wouldn’t recreate the problem. Then going cross country from Colorado to Florida last month the miss started re-occurring. My plan is to just throw in some Taylor wires and hope to get another 15,000 before doing so again. Now that I’m home I just haven’t rushed into ordering parts. I am also curious if Taylor wires without an additional cooling vent system solved the problem for anyone else long term. I'm at the 27,000 mile point now so should probably not complain too loud.

I know that a few owners of 38Rs and 38Ts that have had air flow/plug wire burn out issues have been corrected by the cold air vent kit. The Taylor wires add a layer of insurance and they work well.

That said I have a friend of mine that had a Trek and even though he had the vent kit and the Taylor wires it still wasn't working!

Where would one purchase the vent kit? Are there any pictures of one installed?

Here's what the vent kit looks like:

About a year after we bought our rig, the number 5 and 7 plugs failed due to an airflow problem with my 04 Allegro. I installed Taylor extremes with boots and a DIY vent kit and have put 25000 miles on the rig since with no airflow problem. The vent kit looks similar to the one DriVer posted, but I got all the parts at the local home improvement warehouse.

I had two episodes of burnt wires and WH installed the vent kit no charge back in '07. I re-routed the air duct line to have them flow straighter and took out about 2 ft of extra line. At the same time I added UltraPower and Taylor wires. Now over two years later and 25K more miles haven't had any problems.

My recommendation is to get UP installed. Fix the burning problem, get 50 or 60 more horsepower and maybe 10-15% better gas mileage.

To my understanding no WH owner has had continued burnt wire problems after UP mod ...... with only one exception on a Trek which had vent kit, Taylor wires and UP but it probably had some other problem with fuel/air mixture or exhaust leak or some other complication. Maybe Ohmy or DriVer can give us an update on the Trek case.

Here are pictures of my vent kit installation. This is the passenger side, the drivers side looks the same.

DriVer/Duner-- Reference the vent kit gents, how is the cooling air propelled through the vent line. Is it using a portion of the normal radiator cooling fan airflow? Or, is there only airflow when the vehicle is in motion?

The scoops go right behind your front grille so it gets cool air only when your in motion.

What I understand is that when 8.1L is under full load the exhaust manifolds will be glowing red with lots of heat. Under that condition you'd be moving forward at least 15 mph and would be enough air movement to put keep the plug wires from toasting.

The Trek belonged to Jestme13... He even had small fans attached to his kit and he still burnt wires. The final fix was to trade it off and get a DP.

Air from the grill area is just redirect to the back 2 cylinders on each side of the coach while the coach in in motion... IE - no fans.

i just wonder how many of the rigs that are having burnt wire problems are severely overweight? seems to me that an 8.1 on a long uphill pull that is not severely overweight or that does not have any exhaust restriction problem should not create enough heat to cause the taylor wires to burn. one way to monitor the situation would be to install an exhaust temperature gauge on the manifolds and see what they are actually getting to. temp gauges are not that much use them on my diesel p/u with programmer and on the race cars we work on. would be a great way to see exactly how hot they are getting. then install the fresh air kit and see if the temp improves. but i'm here to tell you if the rig is overweight there ain't much that's gonna help!

I think the problem arises from inadequate grill opening not allowing enough airflow thru the engine compartment. On mine I can also look thru the wheel wells and see the manifolds.

I was at the WH Homecoming Rally near the factory. The service guys told us that it is also related to how the coach is structured just behind the engine compartment. They said if it comes straight down close to the tranny it creates so much drag that there is very little air movement around the back top side. The ones that slope rearward seem to work better. Anyway that's what I recall from last July.
