Hi all,
I was just informed that I have no compression in one cylinder. Is there a possibilities that someone can give me any cost figures if I choose to rebuild?
Parts cost plus/and labor costs for 3rd party to do it. I'm going into this blind.
Thanks
Michael
 
Need to know if it’s a bad head gasket or bad piston or???? Head gasket: couple hundred bucks in parts and a day labor if a shop does it. Engine needs total rebuild, probably north of $5000 for just the engine these days plus labor to remove, install, break in and tune.

Figure out first what no compression means. If it’s a shop and they can’t tell you anything beyond that without “tearing into it”, find a different shop.
 
Hold on to your wallet. $10,000 +- this is why there are chevy V8's


Back in the day $or quit doing F's, 2F were better.

I think my current motor has a sleeve in #5 (leaking brake booster), IIRC I was told they dumped several grand into this motor which I bought for a couple $100 with exhaust, carb starter..

could also be a valve issue
a leak down test would be a better determining factor and give better info
don't assume everyone does a rebuild the same way, get estimates and compare
another option is another good running engine swap, either F, F1/2 or 2F
1974 could have an F1/2, pics would tell what it is

also maybe get another opinion, more of an old school shop that deals with older rigs
 
I’ll post pictures and any info I can find out tomorrow. Hopefully it will help out me getting mods info from the Mud Professors :)

the engine is atleast an F1/2 or 2F, definitely not an F
with no #'s stamped on the block, not sure how else to tell exactly
 
For me the first thing would be to pull the valve cover and see if the valves on that cylinder are actually fully closing. They can get stuck from carboning up, or it could be a broke spring. All of the same type (in. or ex.) should be the same hight at rest).. then the leakdown test). It is more common then one thinks. 🤞
 
My '75 2F heads are stamped 2F. It is on the front by the thermostat, top, driver's side of the valve cover. Just barely not under the valve cover gasket. It is kinda faint.

Alternatively, someone can decode the part number on the air rail side of the casting.
 
I don't know if they did this in '74? Maybe it is stamped by the headbolt, next to the smog air rail inlet? Pic has valve cover removed. This is an '82, but, my Feb. '75 has it too, iirc.

Does your F.5 have bosses on the passenger side for alternator and air cleaner assembly?
Yup, I got that. Probably have those too.

Just went through a blown head gasket. magflux checked, head cleaned, surfaced, replace one bent valve with custom milled 2f valve, hardened valve guides, valve seats, galley plugs, surfaced the intake and exhaust manifold $650 in Denver, Co. and additional $150 in misc gaskets, nuts, bolts, etc. My own slave labor plus $72 in beer.
