[jojimoji]

Aoa, Dear seniors from last week my car mehran mechanical fuel pump get leak and oil spilling out, changed 4 fuel pumps but none of them survive , work for 5 minutes and then get leak, engine oil comes out like a shower
** mechanic checked carburetor, he was saying that idle get was bloked etc etc, i didnt get his point
What could be the problem ?
2 times changed the black gaskit of fuel pump( aka haddi)

[capsat]

your mechanic is CHAY Class champ
he is not installing it with correct Gaskit over the head. and oil is spilling out from that end.

if it is PETROL leaking,

the carburetor need new re-build kit, the float pin & jets either rusted or clogged.

engine oil spill out from this portion

[capsat]

if it is engine oil,
then the oil is seeping to pump base from the blue circle arrow area, This means either the fuel pump gaskit where it is connected to head is not Good, remove & check replace with OEM gaskit, please

Sir, oil is spilling out from the weep hole encircled above in pink color, @capsat sir leakage is not minor, its spill out , at the moment i have put magic solution in weep hole, but pump is not stable on idle

[capsat]

how about fuel pump gaskit over mating slot on head

weep hole oil leakage means oil feed from mating point. @syncview @babarhyd

@capsat sir plz help me out from this musibuuut even the naaami graami ustaad said that this is 1st of its kind in his 20 sala Exp

PCV replaced with new 1,

[capsat]

remove line to carb and check pressure.
if you can buy a scrap fuel pump of bolan & install & test.,

i suspect fuel pump is faulty .. try buying OEM from 3S shop.

[capsat]

you can also check for PCV valve & fuel return line as mentioned by @argtr65 @ Xulfiqar in other thread

Oil leak if positive pressure is produced in engine case. Check pcv valve and it's pipes for blockage, there should not enough vacum to over come positive pressure of back blow of pistons. Other things to check is make sure all vacuum ports of manifold should be properly connected to there respective pipes.if there is any vacuum leak engine should not stable at ideal .
