New Hampshire CMP Barn 2011- 2012 HUP Overhaul

I would have to agree with Alex on heating that head up very hot then welding with your nickel/cast welding rod . then a very long cooling period.

I was also going to mention my experience of looking for low detergent 30wt engine oil last summer. Basicly it was impossible to find except what was labled commpressor oil or pressure washer oil. If it is labled HD30 wt then it was high detergent 30 wt . not heavy duty 30wt.

my 10 cents

Around our area 10 or 20 or 30 non-detergent oil is readily available from farm tractor shops..... stock item for all the old tractor being used.... they claim it leaks less than the detergent stuff.

Phil no doubt that a good functioning PCV system would reduce a lot of deposits....also the fact that when you do run them they are very quickly at there proper operating temperature with the low gearing and tight engine compartment.

On repairing a crack and having it done by a competent machine shop..... I don't think Alex has priced the hourly rates they charge recently ($100 + -)..... Welding the crack, having the head pressure tested and magnafluxed and machining the valve area and installing a new valve seat...... may be cheaper to find another head ........ there is not much market demand for old 216 heads and full engines are usually less than $250...... shipping is the killer.

Offer still stands for parts.....

Hi All

Well I got lucky Obsolete Chevy Parts out of Nashville, Georgia http://www.obschevy.com/index.html had 24 NOS Heads in stock, now they have 23. Numbers say this should fit all 216 41-53 though it will need the later valves which is fine because I was going to replace the valves anyway.

I've had good luck finding odd parts from them in the past, they're the same out fit I got the main shaft for the transmission a couple of years ago, along with some other bits.

Thanks Bob and Alex- I thought about having the head welded and new seats machined in and I suspect with the other work the head would need any way like new valve guides and having the face as well as the intake and exhaust area ground to get good seals that a new head will be about the same cost or cheaper.

Will let you all know as soon as it comes in.

Cheers Phil

Hi All

One of our moderators thought the topic of Welding deserved its own Thread so it has moved to http://www.mapleleafup.net/forums/sh...ad.php?t=16503

So follow over there for thoughts on welding.

On Tuesday I finished tearing the engine down in general it was in surprisingly good condition, measured all the bearings on the crank and they all are measure within .005 of being completely round no real scoring or wear evident but a chip missing from #2 and #3 the thrust bearing as a line across it that looks like a plastic gage line. Did they use plastic gage in 1945? All the bearing shells are market GM with uniform shimming.

The camshaft measures good but looks ugly, so I think I'll let the machines decide what to do with it.

The cylinders had little or no ring ridge though they did have a gum/varnish line above the rings that had to be cleaned off. Used the ridge removing tool but could have removed what was there with a razor blade. All the crank journals look good and measure as being nearly true in diameters what is strange though is that they vary in size one to the next. All the connecting rods have Babbitted bearings the # 1 lower was compete when removed but then started falling apart. See picture. As soon as the new head arrives I'll get the block and parts up to the machine shop.

Today we had our first really warm day 70+ so I pulled the body out of the shop to use the pressure washer on it. As warm water works better than cold for cleaning parts I have added an adjustable hot water tap out side. Used it for the first time today. Really seemed to clean better and it is a lot nicer getting splashed with 105 degree water than the 45-50 degree that normally comes out of the pressure washer.

Hi All

Well I ordered a new head on the 21st and it arrived on 29th. Picture below shows the thing leaning against the shop when I got home on Friday. Had all sorts of labels warning the UPS driver about the weight 71 lbs, use hand cart, lift with knees etc. Appears well packaged rapped in many layers of corrugated card board and wood. Only got through the first layers of cardboard still have to clean the cosmoline off it.

Then I'll load it the block, crank, cam and head in the car and haul it to the machine shop.

Cheers Phil

Hi Phil any more progress on this rebuild?

[Phil Waterman]

Hi Cliff

I have been working away on it though I did not make my target completion date of the end of July. Work on the HUP has been going well with a few real twists and turns. What really has fallen behind though is posting progress photos to MLU and to my web site.

The back log of photos (about 1500) taken of progress and details is huge, now that cold weather will soon be on us, I'll try and get caught up.

And thanks for asking how the project was coming.

Cheers Phil

I am glad to hear that progress is going well and look forward to seeing the posts when you have the time to catch up.
