PILOT BUSHING QUANDRY?!?! So it seems an "oilite" sintered bronze bushing has been specified for our mopar flat head engines. Also, the oilite bushing should be handled in such a way that no damage happens to the pores of the sintered bronze. The link offered by sniper even states that the bushing should be installed with constant pressure and not by hammer impacts. So now I go to my service manual that states the bushing should be installed using mopar special tool DD-286 and driven into place with a soft hammer ( impacted into the bore, a no-no). Then the tool is used to "burnish" the bushing to the correct size. Burnishing is somewhat of a polishing process that would affect the pores of the bushing (another no-no). In Figure 19 of the Clutch Section of my service manual, that is titled "Lubricating Pilot Bushing" it says , "Insert about 1/2 teaspoonful Short Fiber Grease in the pilot bushing." (according to Oilite, another no-no, or at least not necessary). Seems to me the oilite bushing was specified but the mopar engineers knew they were going to damage the pores of the sintered bronze by burnishing the bushing to size and therefore lubrication was necessary. I have and will follow the directions in the Service Manual. Just my 2/100 of a dollar.

I would bet the carb. cleaner in the 1/2 gal.? can will remove paint in a flash and never harm a carb as it was made to clean carbs by soaking the inner and outer parts. Worth a try in my way of thinkin. DJ

Could it be exhaust heat riser flapping around? Wire it in open (rotated fully clock wise) and wire it there temporarily. Might also be the flapper shaft leaking. Remember if you decide to remove the manifold assembly, there are 13 fasteners holding it together. When reinstalling, leave the four bolts holding the manifolds together just snugged. They can then get a final tighten when finished tightening the 13 manifold nuts. Another consideration when putting the manifolds on, tighten the fasteners in a spiral pattern starting in the middle and working outward to the ends. Do not over tighten. Snug them then add quarter turn, start and run the engine to operating temp. When it has coold enough to work on, snug and quarter again from the center out. Then check the 4 on the heat riser. These assemblies heat and cool at different rates, they need to be able to move as they do so. Over tightening prevents this and leads to cracking. Remember the magic number is 13 plus 4(heat riser) When I did mine, I took an old Taiwan box end wrench took out a section of the box like a tubing wrench, and ground it thinner to make it easier to get the nuts that are partially obscured behind the exhaust casting. Good luck.

Carefully check the junction between the intake and exhaust manifold at the heat riser. That gasket can go bad and the sealing surfaces can erode making sealing difficult. Be sure you use the procedure outlined in the service manual when you reassemble the manifolds.

Personally (from all the posts here) I like dogs, but just don't have the time for one. You have to be around (or someone) every so many hours. When we moved to our place we inherited Puma, the shop mouser. She's had her adventures (lost for 6 weeks after a broken carrier outside the vet's office....but we got her back..which involves the USPS phone call...long story). She's my little buddy in the shop and when she's gone, I will miss here dearly. Growing up on a farm I never got too attached to the cats as they were outside animals and could literally disappear overnight. But she has clawed her way into my heart. She's over 20 years old (we actually figure 22 from discussions with the neighbors) now and spends the majority of her day sleeping, but still needs to take a nap at the end of the day on dad while he makes sure nothing will go amiss overnight in the shop after welding, maintenance or woodworking. Hemp oil has given her a new lease on life this last year or so, the arthritis pain is kept at bay and she still plays, runs and jumps. I highly recommend this for older pets! When she's gone, I'll be alone out there, but won't find a replacement as I worry too much about yotes and eagles. I give you the engerizer bunny kitty and shop supervisor: Puma!

Here's my 40 Plymouth pt105 Its just in mock up now Brian

Is it OK if I sneak this one in here? It's a pre-Mopar Dodge Brothers, and it's not a six cylinder... 27 DB

This is my 49 b1, have been working on it for two years.
