Anyone know how to line up the cam on the 1st gen crx FI motor???
the cams are different than all the newer motors, they don't have the same marks.
there is a tdc mark for the crank pulley but i don't know how to set the cam
-
going out on a limb but are you talking about a 1st gen ZC. I could think that you could check the distributor to see if it lines up at the no1 terminal?(assuming its like a normal honda and the distributor only goes in one way. i mean its at least a start??
-
86-87 Si????
Like timing a D15B1/2/7/8
-
i dont think the d15a3 or whatever it was has the same marks as the later motors. and it doesnt have dots or anything in the cam gear?
-
two marks on the cam gear level with valve cover surface and then TDC (white mark) on the crank pulley.
RTFM!!!!!

RTFM!!!!!
it could be 180 off that way...
what i have heard and am going to try is cam marks level with head and the side with the numbers on it facing up.

thats why i suggested look under the cap to make sure the rotor points towards no1 and not no4

UP means up, how hard is that to fuck up????

there is not up on these old cams.

Try looking on the fucking CAM GEAR. Might be easier to see if you take that 12v cam out of your fucking ass!!!!!

why do dumb asses always have to start flame wars. there are no up marks on the cam gear.
there are only twostraight lines and three numbers

Where did I say up marks???? UP is on the cam gear, at least the one I was working on this weekend at Mid Ohio.
-
What the fuck? Hes saying that the cam gear doesnt say ANYTHING about up. Only the side marks, that you would level with the head. So if he doesnt check to see that the dizzy is at #1, he could set it 180* off.

I guess I'm clueless on 1G CRX's.....although #23 is running my 13x6 Rials

I sold Ryan the rims for $100 on the basis they would return to competition, he made good on it!
oops.....

Once again Johnny knows everything.
I guess he is too goddamn dumb to look at cam lobes to figure out how to net set the cam 180 out.

I own Foowee's old 86 Si. Bone is correct, Johnny is dumb.
Johnny, DasShit posted up a MOD pass recently.
Johnny, there are links to Classic Si Helms manuals stickied in this forum.
Johnny, is this your first time working on a car? I don't mean one of your imaginary nine second 52 mpg turbo builds that never have a problem and still run to this day, I mean working on a car in the real world?

I think you went to her neighbor's house, mom's lost a lot of weight due to the cancer. I know it's an easy mistake for you to make, you see a real fatty unloading four dozen boxes of twinkies from her car and you get all sweaty palmed with excitement, don't even stop to check the house number.
Mom's probably lonely if you want to go over there and do some work now, though.

apparently the 86 si is different. because it doesn't have those marks

So you are lazy and complacent.
I see no irony there...

Just put the belt on n go... If you're off a tooth you'll be able to tell by the way it drives.
When I originally purchased the 86, that Joseph now owns, the cam timing was so far off it was causing the car to overheat. I'm fairly certain you have to be off really far to bend some valves.
Also it's impossible to be 180 degrees off with a sohc... the cam spins half the speed of the crank...
-
make sure the keyway is up
-
Yep.
Just like it shows in the 1st pic link posted.
Bottom right.

I want you to think about that statement and tell why you are wrong.

Cause the dizzy drive can be slopped out n put in backwards? If the dizzy key was removed from the dizzy and replaced incorrectly?
I don't see how I'm wrong...
-
on a 4cyl with 90 degree firing angles its possible to be 180 off. only motors i have worked on that cant be 180 off are 3 cyl geos because the crank angles are 120 degrees apart.

Think about this. When if ever will the engine ever have both valves closed on cylinder 1, while pistons 2 and 3 are at TDC?
Never in a 4 cycle engine that I am aware of will you have both valves closed while the piston is at NDC.

both valves will still be closed at the bottom of the power stroke the exhaust usually opens around 30 degrees back up on the exhaust stroke

Not exactly what I was trying to get at, but I didn't think of that scenario.
-
lets just say if the cam is 180 off shit is going to get bent it wont run and you wont ever do it again
-
Okay... 1 and 4 are at tdc. 2 and 3 are at bdc. Flip the cam 180. Which valve events change kids?
-
I have been thinking it thorough in my head, and I was thinking crankshaft 180 degrees out apparently. Different story.
In short you are correct, although possibly too narrow in scope? Now that I think about it, it doesn't matter on any 4 stroke engine.
I R an idiot.
