Heating up a block to get stuck dizzy out
Ok, time to heat the block around the stuck distributor. What is the best and safest way to heat the block with a hand held torch so I don’t crack it? I can’t seem to find anything on you tube.

Re: Heating up a block to get stuck dizzy out
I wouldn't heat the block with a torch at all. The dizzy housing is made out of aluminum, which would melt or become distorted before the cast iron block could be heated enough to expand the opening.
Remove the distributor hold-down bolt. Spray WD-40 all around the base of the dizzy and try to use a pry-bar to push it up between the block and base of the dizzy. You may need to slowly and carefully apply pressure to the pry-bar all the way around the base of the dizzy. Additionally, I would not try to pry the dizzy out by using a long pry-bar against the bottom of the dizzy head. It might cause a crack at the bottom of the dizzy head. |

Re: Heating up a block to get stuck dizzy out
Agree with the method. I think a true penetrant (which WD-40 is not) would yield quicker results. I like PB Blaster. If it's well and truly stuck time and patience are required.

Re: Heating up a block to get stuck dizzy out
It takes an extraordinary amount of heat to heat up a block from the outside. Time and blaster, took 3 weeks and a pool of blaster on a later 400 engine once. Also had 351W on engine stand for couple of months with the blaster and tried heating. Ended up tearing engine apart and driving it out from the bottom. It was a problem back in the day and one of the tool manufactures made what was basically a crow foot and a jack screw that fit under distributor and pushed it up. Wish I could find the maker of the tool or at least a picture. My 351 endeavor turned into a disaster, yes it broke off in the block. Are you just trying to set timing or overhauling?

Re: Heating up a block to get stuck dizzy out
This is a set timing and overhaul. That tool that Late Model pictured is his tool and I still have to try and make it. I will report back when I get the chance.

Use ATF/Acetone 50:50. The absolute best rust buster!

Re: Heating up a block to get stuck dizzy out
Late Model, not the same exact tool but the same principle. Looks like it would work.

Re: Heating up a block to get stuck dizzy out
Just to add my experience to the discussion, I've tried about five or six different penetrating oils on my stuck distributor (over the last several weeks) with little or no benefit. In the past, I've used most of these products on conventional rust corrosion with good results, so it's not like they're substandard penetrating oils.
My goal is to adjust timing (currently 3 degrees retarded at idle) so I don't want to pull engine. I wonder if that tool late model showed could be used with the engine in the car. Last edited by JimNNN; 08-22-2021 at 02:19 PM. |

Re: Heating up a block to get stuck dizzy out
Jim,
I haven't tried it in a car, but I built it as small as possible just so it would. I haven't had a chance try it on my 56, but hopefully will this week. It definitely works great on engines on a stand. I have used it three times so far. Don |

Re: Heating up a block to get stuck dizzy out
One thing I haven't seen mentioned, that may or may not work, just thinking out loud - the Y-Block may be almost unique (at least Ford) in the fact that it has an external oil pump and removal of same would allow access to or from the underside of the distributor body itself. Maybe it would be possible to get some oomph on that thing from that direction and drive it out that way.

Re: Heating up a block to get stuck dizzy out
No one has mentioned this specifically yet so I will throw my hat in the ring here. I too have dismantled quite a few Y blocks and the distributor can certainly be a headache. While there is good wisdom in the idea of not using heat, I have found that if you use a propane torch (not the OxyAcetylene lol) things can get hot enough without damage tho. It does take a while to heat up the metals of course.

Re: Heating up a block to get stuck dizzy out
Yeah leverage and hydraulics always win out. Although the win may not be what you wanted.
