camshaft CLEARANCE
 

hey 86 owners


i had strange clicks from 1# 3# piston side . i think that clicks because of high pressure pump . but day by day and after long high way drive i hear it a a lot . that sound scared me . so Decided Analysis the issue starting disconnect the DI system by using tech stream. whats happened here is the pump stop clicking and that car runs with port fueling system . the clicks from right side shows up and it say i and problem here . OK that worried me and the game start .

engine works from 29/11/2012 with 130k km on clock

- removed the engine
-stand the engine
- remove valve cover
- calculate cam clearance

i found my cam aliment is out of limit as shown blow

limit
intake 0.10 mm - 0.16mm
exhaust 0.21 mm - 0.27mm


what i am looking for is can i use the engine with that issue and keep it without fix the clearance .

Alas! I came in here expecting a good clearance sale on camshafts.

Same.

Good luck on your issue OP.

Did you torque the cam shafts down ??

Then check the clearance.

humfrz

yes as repair manual say 360

Did you check the other side for comparison?

this is what i am doing now

In rare cases check your AVCS sensor as those can go bad and have effected a few people on here.

The OP is talking about clearances... Not a sensor related input. This is a physical measured value that he measured using feeler gauges.

left side


it is bad clearance

What are the ~200 numbers a measurement of?

Havent they also caused cams to go out of alignment?

That'd be the cam position where he checked the clearance I believe.

I'd say those measurements are probably ok .02mm could be normal wear.

that number is standard shim size

camshafts aee in good condition there are no Scratchs or porting marks that let the cam clearance go far .

You have me curious now. I am going to have to check the clearance on my spare block before I tear it down next week. I know a local that is getting a lot of noise when the DI system fires up. I wonder if his lash has fallen far out of spec. It's a shame that you have to pull the block just to check the clearances. Flat engines can be rather painful to deal with. :(

I'm sure if someone was very dedicated you could do it without pulling the block but it would probably take the same amount of time to pull it.

Well that escalated quickly...

Good luck man,

That last picture, is that melted sealant, or did you reseal it ant that's just fresh sealant.?

sorry about it

i reseal it as it shown in last photo

the leaks came from camshafts holder and from bottom of front cover and i apply sealant without rebuilt the engine or remove any parts

after few days i check it and there are no leaks , so it is work ^^ and save $$

I don't mean to bother, but let me get this straight, you're telling me that you basically just put sealant over where it was leaking and it stopped? No tearing of the engine correct? If I'm reading this correctly, that's fucking bad ass!
