My 240 recently started to have some pretty loud knocking sound which seems to be coming from the head...i have a KA24E SOHC so supposedly you don't have to adjust the valve lash. also i don't know if it could be that the timing chain might have to be adjusted...also one of my injectors is supposedly leaking but when i took it to a shop when my engine light was on, the guy told me that he was getting the injector leak code because of my intake manifold and said that i just needed to replace the manifold...i just wanted to inform myself before i did anything...any help would be appreciated...

 

engine knock can be caused from a lot of things. no oil!

i would just check the timing chain, chain tensioner and also, make sure your injectors arent just clicking real bad.
my injectors starting clicking real loud and i thought it was my motor knocking.

 

yeah pretty much what he said. just one question is it hindering your cars performance at all that you can tell?

 

Just make sure where the noise exactly came from. It could be piston noise. If your car have an auto tranny, a bad tranny will also make that knocking sound. Just double check where the noise came from.

 

i ran into another problem...how in the hell do you take out the freakin' fuel injectors...is there some kind of tool you need to extract them from the fuel rail??? i spent half an hour just staring at that crap trying to figure it out...any help as always would be apreciated...

 

oh and to reply to the other posts...i get lack of power from the engine,its a manual transmission, the higher the revs, the louder the knock is, and if it were the pistons, i'm thinking it would just be that the timing of the spark on the power stroke is off, therefore it would have to do with the timing which is at factory spec, 15 degrees BDC i think ...again thanks

 

i thought factory was 20 degrees?

can anyone confirm pls

 

SOHC 15degress BTDC
DOHC 20 degress BTDC

 

if it knocking louder at higher rev it could be your rod bearings.if so i would check them as soon as possible before you spin a bearing.

 

about timing...under the hood is says that the default is at 15 degrees but i have it at 20 but the worst has just happened...my engine ate s--- yesterday...i had to go to mandatory training because of my job yesterday and so i had no choice but to take my car...i can only describe the sound from the engine as the end of its life...anyone know of any places close to los angeles that sells engines for cheap...

 

Yikes man that is defenitely what caused your engine knocking. To little to late.
