L16 with w53 head 4th cylinder not working

[Ed-datsun521]

I just " build" this motor well changed my head to this other block it was 210 engine block and head I figured this would work I searched plenty of times and I went ahead and did it

So I took my old motor off and after I took apart the other one I found the problem on my other engine it had a spun bearing metal everywhere any way I put my w53 head on the block 210 and put new headgasket a new timing kit when I went to start the engine it did not start

I got it to run after but it ran poorly I figured that it was running on 3 pistons (4th is not running) after I unplugged the spark plug wires from the cap on the distributior I have a good spark and I still need to check if that piston is getting fuel how can I check this ? I also to her the pipe on the head on all the cylinders and the 4th one is barely hot at all compared to the other pistons Btw I adjusted the valves all are in good shape going to adjust them again just in case also It back fires through the carburator ? Big puff like when I try to crank it or give it gas sometimes not all the time

Last time when I only replaced the headgasket it ran the same but it was not running on the 3rd cylinder after I adjusted the valves it ran perfect what can I do about what's happening now please any more help can save my truck from getting sold thanks !

Start by adjusting the valves. Do this before running the engine.

 

Next give it a compression test to verify the mechanical part of the engine.

Open W53 on an L16 drops your compression to like 6.5:1!

Mmmm really or is he wrong lol

 

 

 

and btw any way I can make this post go away I feel stupid ashamed and I should get slapped for all the work I did swapping heads new timing chain and I had the fucken wires wrong how stupid please spare me from hazing

 I dont thionk its that bad. 38 increase to 40/41 cc

 

 

I put a U67 head on and its even worse for compression but runs GREAT!!!!!!!!!!!

truth come out you were messing with it!!!!!!!!and didnt tell us exactly what you did. We need to know this.

some come on here I drove 450 mile then this happens. Oh for got to tell us you pulled all the plug wires and now they wrong(this is a example)  i did this myself on a Capri 6 cylinder Doh!!!!!

 

 

anytime some one looses a cylinder alwasy ck the wire .plug valve lash pad fell out or the exhaust vale getting tite(over time the seat will sink and cause the valve to not fully close)

Pretty hard to swap a head without pulling the wires.

 

L16 with

 

210 head............... 8.58

Closed chamber..... 8.21

Open chamber....... 6.72

[banzai510(hainz)]

leave wires on dizzy cap

1234 front to back

[Ed-datsun521]

The block that spun a bearing had flat top pistons ? With valve clearance

This 210 block has dished pistons oh well 75$ Was. A good come up

[wayno]

99.9% of W53 heads are closed chamber, it will run fine if everything else is good.

[Ed-datsun521]

Yeah is a closed w53

[Z-train]

Almost perfect for a huffer or a pinwheel.

[ggzilla]

8.21:1 compression ratio is good. Will run well and make good power.

[datzenmike]

Yup. The L16SSS engines had closed chamber heads and flattop pistons to get 9.29 compression with dual SUs.

I guess I'll just rebuild the other block with new bearing it was a fresh rebuild but when I took it appart I found one of the screws on the oil sump was off and the oil and it was loose so I think that lead to premature failure of the bearings that way I can get my flat top piston block back together

 

I just test drove the truck and it runs pretty good just a lil slower than before but the other engine was not running optimal with out the oil getting distributed

 

And hainz the truth was always out I said up on the first post I took the whole engine apart
