4.6 high miles
I am new to the whole OHC motors, I know some about them but have only owned pushrod v-8's so far.
Anyhow my qeustion is how many miles can you get out of these I have a line on a 1991 town car and I know it's not a truck but this is the site I go to for all my ford qeustions, it has been taken care of and runs good but has 200,000 miles on it and before I drive three hours one way I would like to know anything anyone has to say, I have taken a couple of 302's past 200,000 and my 1986 E150 302 had 270,000 plus and everything but the motor went out and it didn't burn oil and would fry both rear tires. thanks for any input, advice, or heads up.

I ran my 97 4.6 to 170,000 and sold it to a friend and he has put another 35,000 on it and the plugs, air cleaner, etc. have not been changed --- ever. The oil, filter, wiper blades, front brakes, and tires -- that is it. He loves the truck and it still runs great! Good Luck

4.6 high miles
My parents have a 92 Twncar with 217k miles.
I'm not normally a Ford guy: but I like and respect all models-especially the performance ones.
That car has really won me over as far as SOHC and DOHC engines are concerned. I really like what Ford did with their OHC engines. It is pretty easy to work on: no engine brackets was a pleasant surprise when accessories fail-makes it pretty easy to replace components.
The only beef I have had, working on my parents car, is when a coolant leak ocurred between the trans bell housing and converter. In my past if I saw this kind of leak my immediate thought is a freeze plug in the back of the block just behind the flywheel.
Well, to my surprise after going to the extra trouble of pulling the trans and flywheel....all freeze pluges where good to go-so, where was the water coming from? Turns out ther was a coolant hose routed under the intake manifold. Ford knocked out a chunk from the back of the block about the size of a silver dollar: this way when this particular coolant hose breaks-the water will have somewhere to go instead of soaking all the electricals under the hood. Yea for Ford-boo for me as I still had to put the trans back on....went ahead and put new freeze plugs in anyway.
Turns out Ford decided to route the coolant from the back of the water pump, under the intake manifold straight to the heater core.
This required pulling the intake manifold, locating a shop that can recreate a pressure hose fitting. One end of the hose is a pressure fitting while the other end is simply held on by an o-ring clamp.
Other than that pesky coolant hose-I really like the ford V8 OHC engines. BTW-that hose busted shortly after the mileage passed 200k on the odometer.
Something else I like about Ford's OHC engines is how they used timing chains....instead of timing belts. Seemed like every mfg of the 80's chose to use timing belts on their V6 & V8 OHC engines. I was pleased to see Ford go the way of a timing chain-means a much longer lasting engine w/out worry of ever busting the timing belt.
Hope this helps. Dont know much about the pre 92's. 92 was the year for new changes on the Twncars.
Kevin,
