checking out an 86 mk3 tomorrow

When you torqued down the bolt did they move smoothly all the wayuntil you stopped or did they stutter or skip? It's important.


The CPS is easy. Here's how I do it broken down into tiny steps:
Remove cap so rotor is visible.
Line up circle indicator with notch on the other end.
(I don't do this, but you might as well) Use a magic marker to place a mark on the rotor and on the CPS/Dizzy housing so you can relocate/verify 0? easily if you need to.
Now, insert the shaft in the hole...
Giggle like a girl. (optional)
Before seating the CPS/Dizzy, rotate the whole assembly so the CPS/Dizzy retainer bolt's hole is in the CENTER of the eccentric opening.
Now, as long as the rotor is still at 0?, insert!

NOTE: Due to the cam and rotor's helical gears the rotor will rotate a little bit as it turns. If it doesn't line up very close to 0? when inserted try backing it out and rotating the rotor just a hair clockwise or counterclockwise to correct for the rotation. Mine's not dead on, but it's only off by 1/16" or so... With the dizzy lined up to the center of the eccentric bolt hole my timing is pretty much at 0?. You don't have to do it this way, but it makes things easier sometimes and you can then confidently mark the CPS/Dizzy housing to reflect where 10? is.

Bah.... the alternator... not paying attention here eh? Sorry... that's even easier, but I think the TSRM covers it fine. I'll look it up.


EDIT: Well, it's a simple job, but the TSRM may not explain it well enough, I dunno: http://www.cygnusx1.net/Supra/Librar...aspx?S=CH&P=17

The only trick is that there's a metal bushing in the upper mount which presses inward as you tighten the top bolt. If you have trouble getting the top pivot in us some pliers or a small C clamp to press the bushing back out of the gap... it'll close back in when you tighten the bolt down.

bolts moved smoothly all the way. used the goooooooooy stuff they gave me. did it in 3 passes also to make sure everything was tight.

*turn key*

rev rev rev rev..... POP

smoke........

sorry folks but this maybe be it. maybe its shop time

Okay... I'm just the paranoid sort; It's served me well over the years.

Well, don't blame ya if you do, but I'd go over it all one more time... you're missing something. If it's back firing through the intake either the mechanical timing is off or the plug wires are installed in the wrong order.... same thing's likely if it's doing it out the back too actually.

I'd go back through the TRSM's reinstallation segment and double check everything. http://www.cygnusx1.net/Supra/Librar....aspx?S=EM&P=1

Make sure you do not over tighten the timing belt tensioner pulley, it will distort the #1 cylinder rather easily if tightened past specs.

i dunno cre. im kinda scared to see whats dead now. there was smoke in the engine and no power after last night. grrrrrrrrrrrrr

[cvbikeguy]

ok so my friend says that the smoke is nothing. grrr

"keep trying"



ok so. lets think this through again. the cam gears should be pointing up as the crank is at 0. right?

i take the cap off the dist.... sh*t as i was reading i was going over cre's other post.

"Line up circle indicator with notch on the other end."

circle indicator? that little hole inside the dist?

i lined up that little notch with the other little notch on the side...

God im hopeless

[cvbikeguy]

car started. lot of smoke only at the exhaust area of the engine. idle a little funny bot not too bad for not having the timing adjusted yet. put it in drive to move it out of the garage. no go

barely started to creep

[cvbikeguy]

no oil pressure
