hy to all... how to know the apex seal worn? what is the syntom? thks.. cheers

 

Low compression over all three faces of the rotor is one sign of worn out Apex seals.

You can look at the apex seals by removing the exhaust manifold and looking through the exhaust ports.

 

welcome to the board.

run a compression test.

 

when doing the test take the valve core out of the compression tester so it doesn't hold and build up pressure(ie you are checking each face as it makes compression). you are looking for equal pressure readings in the 120-90 psi range.

3 solid pops means all good on each face.

2 weak one solid shows a broken apex seal

1 weak 2 solid shows a broke or stuck side seal

3 weak pops means worn seals

other conditions exist beyond these but this is a guide line

Symptoms are hard starting and lose of power.

 

thks for u all information... nice info..but still need more idea from u all.. thks.. cheers..

 

There is no more ideas to give. You either need to describe your car's problem (include what model you have) or do a compression test.

 

the problem is sound "week to crank" the engine but it start after a countinues crank..it also sound the battery are week..but after i run the car,(should the battery charged itself)but it did'nt..the engine still week to crank..that happen on my stock 13bt fc3s engine..so need advice..thks..

 

if the battery is known to be in good health and you've been on top of tuneup maintenance, then i think the only thing you should be worried about right now is getting the compression tested.

how fresh (mileage) is the engine?

when was your last tuneup?

 

You should also check the Alternator connections, and have the alternator tested as well.

 

yup,i will do..thks ya bro..cheers..
