351 engine tear down
#41
So I found the cam I need, good point, the clouds slowly dissapear, but the way is still long.
Still no news from Alex's parts, but what I know they are running out of valve guides.
I sent them a reminder with the cam specs to be sure they send me the right parts.[/align]

Refering to the excellent book "how to rebuild..." by Tom Monroe, yellow stripes on valve springs belong to the 351 C 2V engine. So looks like my 4V heads have been touched by a bad mecanic Sad

I used 600 sand paper on the crankshaft, still need to continue but looks like I won't need to grind it.

Any tricks available to remove the camshaft bearings without using the proper tool?
The only way I see is to use the old camshaft and set it upside down but it looks dangerous to me to do that way.

Not necessarily, just becase they have yellow on them doesn't mean much of anything after 45 years, they could be almost anything by now.

If there tiny marks on it, it's best to have a crank shop polish it . . If your bearing clearance is too big, you can get .001" over sized bearings or use standard bearings in one side and a .001" over bearing in the other . . Also, if you do it yourself, I would use wet dry paper and wd40 or water.

I use WD40 together with the sand paper.
I found out that one oil passage on one head was plugged with sh.., in the front of the head, it's where the main bearings are marked.

I wait for some good calipers and other professionnal tools to measure exactly all journals. Then I will see if I do it my self or send the crankshaft to the mecanic.

Don't want to get into any pi$$ing contests, cause most of the time these books are on the mark with their info. But Tom is wrong on the springs. The C9OZ-6518-E 428 springs Ford used on the M & Q 351's were marked with silver or yellow stripes. I installed a set of Boss 351 valve covers on my NEW 1972 Gran Torino Sport with "Q" 351 and I remember yellow stripes on the springs. Back then I didn't know what that meant or why Ford would paint valve springs???!!! Lol

A light update:
About those springs I change them, waiting for Alex's Parts springs, valves, valve guides and more.
The crankshaft is to the machinist and now I wait his call to see how he will have to grind it, then I know what I need to purchase right rod and main bearings.

Crankshaft is done, will pic it up to the machinist those days.
I received all parts from Alex.
About the heads, I need to find someone who could ream the valve guides to insert the new ones. Is there a special tool like a guide to do this job well done?

Nice car show, where is that?

valve guides are thick and the head must be machined to install them.

valve guide liners are very thin and are bronze and the guides cam be reamed with a reamer and 1/2" drill and they can be installed with the proper tool . the end the tool is n sometimes needs to be reamed slightly with a tapered reamer to remove any metal that was smashed over when they were installed.

your seats will need to be recut.

i always lap in all the valves after cutting them.

We have near home the monthly meeting. Was a lot Mustang, but the only proud owner of a 73 model Tongue

I picked up the crankshaft, freshly regrinded, ready to receive new rod and main bearings, 0.010 undersize.

Heads still need to be machined to insert the valve guides (i choose iron one and not bronze), and hard exaust seats.

Then I will order the sealed power CS 650 camshaft, hydraulic lifters, rings for the pistons, and I will be ready to rebuild the engine.
