james curl Posted March 28, 2013 Report Share Posted March 28, 2013 Don't do it until you need to do valve work or re-ring. I do not think you will find any carbon to speak of in the head or on the piston unless you are burning oil. With compression at 125psi across the six cylinders I would be reluctant to mess with it because these engines are hard enough to torque and keep sealed.

Plymouthy Adams Posted March 28, 2013 Report Share Posted March 28, 2013 (edited) I dare you!...I double dare you!...I DOUBLE DOG DARE YOU!!!.... Its a matter of pride. You have this performance part sitting on a shelf. WHY? Why do you have this car? It's a hobby, it's a challenge, it's what keeps our minds sharp.... It needs to be done. Not because its broke, not because its slow, not cuz its needs beautification..... Its needs to be done because that's who you are....a car guy! Now get your "no frills, common sense tools out" and give us a tear down report on a great running engine. 48D it's jut the thing to have on your shelf that drives everyone else crazy...lol it's cast iron, eats nothing, can't go anywhere on it's own..it will be there when needed.. Seems some folks can't stand prosperity.. No sense to eat the eggs if you need chickens on the farm..

Don Coatney Posted March 28, 2013 Author Report Share Posted March 28, 2013 give us a tear down report on a great running engine. 48D I can do that without leaving my desk chair. Here you go and I will try and be brief. Was running great. Tore it down. Found and fixed nothing. Put it back together. End of report.

James_Douglas Posted March 28, 2013 Report Share Posted March 28, 2013 Don, I would be interested in knowing how much tapper at the top of the cylinders you have since the original rebuild if you measured it. I have an 86 year old machinist here just south of "Frisco" :-) that tells me that the blocks on the flathead six's seem to go out of shape relatively early due to soft cylinder walls. So, anyone that built one up in the last 10 years and thus uses new oils and rings...and then pulls off a head off after 5K or 10K miles...I would like to know how much of a ridge and/or the actual tapper they get. Best, James Quote Link to comment Share on other sites More sharing options...

Desotodav Posted March 28, 2013 Report Share Posted March 28, 2013 I'd be putting the Spitfire head on Don as I don't reckon that I could have something that good sitting around my place without being on the vehicle! Surely Murphy's Law doesn't apply all the time! Just as a matter of interest though (for someone not very mechanically minded like me) - I believe that the Spitfire head will increase your compression, do you have to do any other minor adjustments like changing the timing or modifying fuel mix etc after you put a performance head on?

Labrauer Posted March 30, 2013 Report Share Posted March 30, 2013 Back in the days to get rid of carbon on the valves and pistons we would set the throttle up a few RPM's and pour some ATF down the carb slowly till the car would almost die or would die. Let it set a few hours and crank it back up and boy would it smoke but the carbon would be gone. After a few minutes of running it the smoke would clear up and besides the smoke does wonders to these Texas size mosquito's around here for a while.

I have never heard of pouring ATF in the carb, but have heard of spraying a little cold water in the carb. Quote Link to comment Share on other sites More sharing options...

A guy I know mixes ATF with one tank of gas once a year for his Indian Motorcyle. He swears it keeps his heads clean. I haven't tried it, but I wiould like to know for sure if it works.

larryconnors Posted May 21, 2013 Report Share Posted May 21, 2013 If I have a good running, good driving car during prime season I drive it. If I have a problem that takes it out of that category I fix it. If I have nice to do that won't take it out of that category, I'll do it. If I have a nice to do that may tie up my car for awhile I'll wait until the off season to do it. That being said, I'd do a proper fix on your radiator and wait until the off season to do the head unless you are confident that you can do it quickly without complications..
