2F head

[apeterson]

ok just a quick update...... got the engine running.... about 5 min at a time... 2 times... so 10 min total.... still no oil in top of engine.... rocker arms seem like they are getting somthing... but not the top of arms and springs.... my dad (not a cruiser guy, but an engine guy) says to keep running it and it will take longer to get the oil up... is he wrong? what is my worse case senario? should I be worried??

I would worry. 5 Min of running with no oil dripping out of the rocker arm sounds like a problem to me. The oil pump should pressurize the top end in less than 15 seconds.

I wouldn't run it anymore until I figured out that it WASN'T bad....

No easy suggestions:

Pull the dizzy and pump the oil up with an electric drill? - That's hard - and possibly risky if you don't put it together right. and if nothing comes out, you still have to pull the head...

Pull the head, and ensure all oil passages are clear? That's hard.

Can you remove the rocker assy, and see if oil is feeding into the tube? I'll bet that's hard too, and then you have to run the engine more...

Maybe someone else has a good (easy) suggestion.....

I've never seen a 2F that will show oil flow at the rockers on initial start up within 15 seconds. But 5 minutes is longer by far than it should take.

Popping the distributor out and spinning the oil pump with a drill is easy. But it's a crap shoot as to whether that will oil the rockers anyway (the camshaft needs to be spinning for thre oil to pass through it.

I'l dump some oil over the rocker assembly to keep from damaging anything, and run it for a while.... Assuming that:

You made sure that the headgasket got installed correctly. If it's put in backward/upside down the oiling passage is blocked.

You're sure that the distributir is seated in the pump and that you have oil pressure.

I am not sure the head gasket got put in correctly.... I assume the only way to ckeck that is by pulling it all out...

where is the oil pump and how do I make sure I have pressure....

 

[Mark W]

There is about 1/4 - 1/2 inch of head gasket that sticks out at the back of the head when it is installed correctly. AFAIK, all aftermarket head gaskets are this way to, but maybe not (this would help explain how people manage to put them on backward in the forst place).

The oil pump is... in the pan. If you are asking because of the comments about spinning it with a drill... You pull the distributor anddrive it through there. The bottom of the distributor shaft fits into the oil pump and that is what spins the pump. If the distributor is not completely seated on the bolck it will not ingage the pump and the pump will not turn, resulting in no oil to the engine.

For oil pressure... check the gauge.

While it doesn't tell you anything about the pressure, you can easily check for oil flow itself byloosening the oil flter. If it's ful of oil and starts leaking a mess all over the side of the engine... You're getting oil from the pump.

let engine run again today for 15 min... I put oil on the rockers so that everything was lubed up... no extra oil is comming to the surface... the oil pressure gauge goes to about 3/4 to the top of the gauge... so I assume it is reading correctly... pulled off the oil filter and yes there is oil there... so I know it is getting around...

going to check in the morning to make sure that all head gasket is sticking out the back... I will post in the moring what I find out..

I wouldn't worry to much. It's not good, but it won't damage the head (short term).. I had a '74 F motor that I rebuilt (first motor I ever rebuilt). We'll the head gasket appears to fit two ways, but to the trained eye one will block the oiling to the head. I drove 600 miles on the motor out to Death Valley and back before I realized my mistake of blocking the oiling passage to the head.

I would definetly fix your problem ASAP.

 

[apeterson]

yea..... I can not tell if the head gasket is put on wrong... there is nothing sticking out as Mark stated... so I guess my next thing is to pull the head... do I need to get a new gasket or can I just look at that one and see if it is the problem and flip it over...

if I order a new one, how do I know which one to get??? I mean do I get a number off the head or somthing?

 

[Mark W]

Back at the beginning of this thread ou were asking about mixing abd matching blocks and heads. Are you sure that you have a '74 F engine? Are you sure that yiu have a 2F head? If you have put a pre '74 F head on there it will not have the oiling passage drilled in the head.


Mark...

 

[apeterson]

no I am not sure... not sure at all... going off of what the PO told me... it was not him that put the head on there it was the guy he bought it from... who he said was not very trust worthy.... how do I know what i got??? I am wondering if it is just the valve cover.... the head and block are painted the same greenish blue color, I can not imagine that is the factory color? is there seperate marking on the head and engine?

 

[Mark W]

You can't assume that you have a 2F head just becasue there is a 2F valve cover on it.

Look at the front, driverside corner of the head. On the top, beside the valve cover. There will be either "F" or "2F" stamped in the milled flat spot there.

[apeterson]

Thanks mark... I will look tonight...

 

[apeterson]

ok I looked around on the driver side in the front and I could nto find a 2F or F... here is what I found.

on the block are the numbers 60035 and 11411 both of those are at the driver side front, there is also some kind of symbol, can not quite make it out, looks like a F 3 17 all in a circle????? on the rear drivers side of the block is are the numbers 50913, below that is the number 31

on the head the number 600051 and a little to the right of that is the number 3305 and below that is number 35......


do these make sence to anyone...

back from the deep...

any thoughts on using a 3F(E) block under a late 74 F head with the 2F oiling system? just wondering.....

 

[grant5127]

The oiling will be there......
Not so sure what the compression ratio would be with the flat top pistons tho....
Have to ponder on that, could be piss-poor...

by the numbers, the comp is almost static. I just dont want to let the 3FE block go to waste and I've got almost everything I'll need to do it

Never reuse a head gasket. I was taught many years ago to replace the head bolts any time you change gaskets. Cheap insurance against an old overstrtetched bolt breaking.

As for what gasket to use, get a good one, not a chinese partshouse special.

I disagree. I think you can use the LandCruiser headbolts many times without overstretching and breaking...
