what a disappointment
29 Tudor, stock except for FSI electron ignition. Have had car for 7 years without any major problems. The problem is overheating when idling more than a few minutes or cruising over 45. I have a temperature gauge and have double checked with a handheld probe. Over the years have flushed , back flushed , ran vinegar, distilled water, antifreeze, timing has been checked, double checked with TDC and has made no difference. Can cruise all day 40 - 45, run around town no problem unless I have to idle roo long.
Last year the radiator developed a leak around the upper tank. So this year I bit the bullet and installed a new radiator from Snyders and opted for the heavy-duty. For good measure also changed the water pump. Thought well happy days are here again. Nothing has changed, still has the same issues as above. I guess this means there is internal problem with my engine, any suggestions other than just enjoy what I have. |

Re: what a disappointment
Where are you running the spark lever when idling? Don't retard much when idling. Listen to the engine, it should not be "laboring". Advance until you hear the ping then retard just until ping goes away. It should not overheat, EVER. I can't make mine overheat. Original radiator and all stock.

Re: what a disappointment
If I had that problem, and have already made sure it is not that the timing is off, I would pull the head. Your head gasket and upper block cooling passages could be severely obstructed. Retarded timing can heat things up pretty fast.

Re: what a disappointment
I would take off the head. It isn't very hard and will give you a chance to see what is going on in the block. My Dad had at 29 Roadster that couldn't stay cool, did much of the same things you have done, when we pulled the head, we found the head was missing a hole and a few others were not as large as they were supposed to be. we drilled the missing one out and cleaned the others up. it ran cool from then on. You can use a head gasket to see where and how large the coolant holes should be and if one is missing, as was our case.

Re: what a disappointment
I have electronic ignition, spark is automatic and it does work, have checked it running with a timing light.
Hate to pull the head but it may come to that |

Re: what a disappointment
Ya I laugh too! I spent about 8 hours working one off. Don't think a head puller would have worked. Even had it suspended from a cherry picker. But if the head has been off in the past few years, maybe. Suggestion, drain the water, turn the head nuts up about 1/8 off the head and start the engine. Lots of times the bang or two will pop it loose.

Re: what a disappointment
spark is automatic There would be my 1st suspect. Hook up the manual lever and try it before you do anything else.

Re: what a disappointment
I run a stock distributor but I have had a little experience with the FSI Distributor.
Most of these have way too much mechanical advance. If you set the advance at 30 Deg. at 2000 RPM, the distributor will have zero advance at idle. A Model A engine needs about 16 - 18 Deg. at Idle. Running zero advance at Idle will definitely heat up the engine if left to idle for a long period of time. FSI now has different springs and advance parts for their distributor to better set the advance curve so there is some advance at idle. I would suggest you get rid of the FSI and install a good original system. Time it correctly and use the Spark Control Lever as outlined in the Instruction Book (Owners Manual) and you may find your car runs better and cooler. Automatic advance distributors are good IF THEY ARE SET UP CORRECTLY. FSI is notorious for having a very poor advance curve built into them. FSI thought the advance should be about 30 Deg. when running (which is correct) and no advance at Idle (which is NOT correct). Again, this is JUST MY OPINION.

Re: what a disappointment
When it runs hot shoot each cylinder water jacket with the heat gun. Shoot the head also. Look for high temp on #4

Re: what a disappointment
I like stock,the way Henry made it,put the stock distributor in and give it a try before pulling the head.A lot of times the head is stuck fast,I lifted the front of the truck by the head and still wouldn't budge.

Re: what a disappointment
I notice on here that many times the problem is caused by what ever is changed from the way Henry did it.

Re: what a disappointment
I have experience with the FSI self advancing distributor as I have set up a few for myself and customers.
The FSI website states their self advancing distributor has 26 to 28 degrees advance. If you are setting the spark timing at running speed (in advanced state) and you are setting it to a conservative 24-26 degrees advance, you may be running close to zero advance at idle. This condition will cause overheating. From my own experience, at idle you should have a minimum of 5 to 8 degrees (more is a bit better) advance or the engine will overheat. It is also possible the distributor is set up with heavier springs which will keep any advance from the weights from happening until the engine RPM is raised over 1100 rpm. This will keep the engine retarded too long and has the same result. An earlier post suggested trying a stock distributor. I know it takes a bit of rewiring to do so but trying one would let you know for sure whether your problem is the distributor. I had the problems I am describing above with one in 2013 when using a high compression Lion Speed Head. The head was sensitive to too much advance so I retarded the FSI Zipper (set up with the heavy springs) and that put the spark timing at zero advance when idling. The engine would quickly overheat. I had installed the Zipper FSI so my wife could drive the car prior to starting a long road trip (9700 miles). She never got behind the wheel while we were on the trip so when we returned home, I took the Zipper off and replaced it with the manual advance distributor I had on the car since I restored it in 2000. A negative to a FSI Zipper distributor is that you do not have the option to retard the spark a bit when necessary at the long hills. Most times, closer to a stock system will give you less troubles. Hope you solve your problem soon. Good Day! Last edited by Dave in MN; 04-25-2018 at 07:32 AM. |

Re: what a disappointment
The head needs to come off and most likely the block needs to be boiled out. This is a common problem which like us the arteries get clogged up!
Ignition has nothing to do with this symptom. |

Re: what a disappointment
I'd also check idle air mixture. Lean conditions can run on the warm side too.

The Model A cooling system just like the fuel system is very sensitive to any problem with flow. |

Re: what a disappointment
Judging on your own experience with your engine over a long period of time, it is probably just the head gasket. The last 3 or 4 that I have done have come off fairly easy. Perfect time to check everything out on the top of the engine. Take the distributor out and the top hose. You don't even have to take the waterpump off. just the fan belt and away you go. If you are at all handy it really is not that big a deal. Spray all the fasteners with penetrating oil the day before. Look at the rotor and put the distributor back in with it pointing in the same direction. If you have the parts you can easily do it in a weekend and be driving it on Monday.

Re: what a disappointment
i used the Bill Stipe head puller, and broke it. i chained up my heat to a chain fall, all that did was lift the car off the ground, i jumped on the bumper and no movement. after i got the head off i had to replace the studs. luckily i got them all out with out breaking any
