Lincoln "L" Technical Questions

Cylinder Head Removal
Author Last Post
Linus, I feel your pain and it is no small matter taking this L engine down. I keep having a leak around a head bolt that runs through the exhaust manifold. I have been trying to solve this one for some time. I thought I had it, drove hard and no popping. Put my wife in the car to show off, 1/2 mile and it starts to pop. I am going to work on a possible fix for this using a machining option. Will keep all informed when I get it.

Jeff- well done. Patience, penetrant oil and gentle persuasion over time. I recently freed up a stuck 1941 John Deere by using a penetrant/diesel fluid mix, and just going out every night for a month and gently rocking it.

Will want to see pics and progress please.

i was just going to talk to you about what you have already done. Keep us posted on your progress.

Ive just torn down my entire engine top end, blocks, rods pistons etc to chase a knock and put it all back together to find no change. Very frustrating.

Success!!! I got that big son of a gun off! Sorry for dropping out of communication. Between work and my 25th Anniversary vacation I haven’t had time for this project. I used a lot of Permatex penetrating oil to around the studs. Rubber mallet (my right arm is tired), and plastic wedges. Then I used something that rarely surfaces in my shop: patience! I did a little bit at a time. More penetrating oil, more tapping on the plastic wedges, more banging with the mallet. The lower front edge started coming right away so I thought I could just keep working my way around it. I didn’t take the exhaust manifold off (yet) because that seemed like a recipe for hard work and frustration if the studs were to break. The head is heavy! I should have used my cherry picker as one person advised, but I went with the manual method.
I’m trying to get good pics of the cylinder walls. There is one minor rough spot. A vertical line of very shallow pitting like roughness.
I am going to take the rod and piston out. It is the left side, and if I read correctly that is the “fork” side and no adjustment is to be made to that, so I’m not worried about assembling it too tight or loose if I get that far.
I will continue to update. I still owe Linus a call too!
I agree and am guilty of carrying the conversation off the site.
It appears that Jeff is trying to remove a head on a Lincoln L that is being stubborn. It will be great if Jeff can take some pictures of the head once removed and the cylinder walls, etc. He lost part of a piston skirt and I am curious as to if this scored the cylinder walls. It may not have.
Looking forward to updates from Jeff.

It could be helpful to other LOC members if the conversations and successful procedure Jeff had regarding his cylinder head were posted on this forum.



Thank you to all the folks that helped me privately! I was lucky enough to be included on a group email of LOC members and I asked them and received great help. I think we need to find a way for this forum to reach more members. There's a wealth of knowledge out there with people willing to help. Thanks again, it's starting to budge!
Help! I'm trying to remove the left side head on my beloved 29 Lincoln. I am pretty sure the engine has never been apart. All of the nuts came off without a problem. I thought it wasn't going to be so bad as water trickled pretty steadily out of the left front and corner. I sprayed Permatex penetrating oil in all of the stud holes and let it sit for a week. I have hit it with a rubber and wood mallet as much as possible, but that's fairly difficult as the studs are spaced pretty closely together. I have started to drive in two thin plastic wedges in the area that leaked water. It won't budge. This is where I have chosen to stop so as to not compound my problems. It seems like heat would be the next step, but I'm not going that route until I get some educated advice. I guess the final step would be to build some sort of puller using the spark plug or primer cup holes to apply upward force.

Thanks in advance!
