well not really found it yet... but everything checks out and are in specs so only possibility is that my starters have seen better days...putting it back together now with new hd starter that have gear reduction.
bit more update...
bore is straight no taper...rods are oil hole in sparkplug side should be ok?
tryied with plenty off redline assebly paste to bore and piston no difference could it be that oil ring is causing this...when you look at the KA24 oil rings when you install thin rings both side of the "oil ring" they wont go deep enough to the piston anymore??
i was using normal engine oil for assembly would assembly lube make so much difference?
you can turn the bottom end in the stand from the crank if you take VERY good grip with two hands...but its way more hard than my complete old l24 with plugs in
Ok update
i took piston rings off and put pistons and conrods back and torquet everything to spec...smooth and easy to turn
piston ring cap is ok tho upper about 0.45 to 0.5mm second about 0.55 to 0.6mm
dont understand how they could cause so much frigtion that my old l24 is easier to turn even with head and plugs in
transmission should be ok...gear was free when tested.
i believe problem was conrod bearings all should have been standart but there was some quality and size differences between the bearings
ok
engine is off and pistons are off
you can turn the crank quite easily by two fingers...so i believe main bearings are ok i didnt find any markings from conrod bearings and they look good
alternator was upgraded before i swapped the engine was running good with my old l24
yeah wires getting hot would succest bad wiring or connection but main wires and connectors are new
and i am running/testing starter directly from battery not by key...
it turns like there is no power but battery is full 12.8v and tested another good battery also even with jumper cables so these should be enough power to turn the engine
Hi
I tryied to find topics for this problem and found few but they did not help me...
i have very hard time to crank the engine tryied 2 different batterys and 2 starters ground and + should be ok
even plugs of engine turns hardly and + wire and starter gets very hot after trying.
engine has never run just fresh rebuild
n42 block 89mm bore
240sx pistons
n42 head
1.2mm metal gasket
is there any possibility that my timing chain could be to short i remember that it was very difficult to but on
and that causes to much frigtion?
bore is to tight? that means i have to take engine of
can somesort head problems cause this??
