i bought the vue for parts really. new exhaust and tires. i wanted to see if i could fix the heads actually and move on. i only plan on driving it to verify it is fixed. 1-2 weeks than its gone

my vue use the 3+ coil pack for each bank. i do not know what the test procedure is for these types of coil packs. another tech says my heavy carbon/crud residue is probably due to bad rings on that cyl.

Started vue this afternoon. It purrs now. Clatter sound is gone. With 100% new exhaust, vue is so quiet. So, how do you verify weak spark on cyl #3? I have no misfire codes. But combustion chamber looked bad when I pulled head. Should I just try another coil to be safe?

thats true. what happens in cylinder? fuel is injected and spark ignites it. too much fuel and/or weak spark can work together or independently to cause the issue. does cyl also have good compression? i cant really verify ring condition unless i do a leak down test. i got vue as a flip. fix obvious issues. i didnt feel like putting in a rebuilt motor.

motor was not running when i got it. pulled heads. bent intake valves. cyl 3 had a major amount of black carbon crud. 1/16" layer on exh valves faces. cyls1-5 looked normal. almost no buildup. front head or 2-4-6 looked ok. talking combustion chamber appearance. i also noticed the front bank O2 sensor had a white buildup while the rear head sensor had a normal black sort of sooty look. coolant leakage? cracked block? cracked head? no i did not have heads pressure tested since it was a bad timing belt that was my main issue.

it is running. my kid with identical vue was over yesterday and i changed a wheel bearing. her vue motor makes the same sort of clatter/tap noise. is it noisy fuel injectors? cam/lifter clatter? motor does not exactly purr. hmm, i hope it checks out ok in the next few days.

I ordered a 14mm hex bit on eBay. $6 delivered. Duh. I meant to order 12mm. I don't need a set of bits from 8mm-16mm? My dad has $50k pile of tools. 80mi away.

i cannot post pics. but, the old casting has the hex roller directly above the water pump centerline. now it is about 1" to the right. the distance between the roller and the cam sprocket is about 8mm.

Cast alum bracket/2 rollers is 2 weeks old. Are you saying replace them? Former owner changed timing belt, bracket, rollers, drove it for 2 weeks and it jumped time. Bent valves. Have not figured out why timing went.

Well, I do have 2 new rollers/bearings and 1 old roller. It would be good to have all new rollers.

i think ALL the online videos show the adjustment procedure for the timing belt with 2 hex rollers. they use the upper roller to tweak bank 1 cams and use the lower roller to tweak bank 2 cams. i cannot find a procedure that adjusts 1 roller only.

i think saturn used the 3.0 motor in the L300 sedan prior to 2002? perhaps it had a single hex setup?

do you have a link to the 1 hex adjustment procedure?

the way it is explained to me is all motors have tolerances. some have stock heads, some may have milled heads, some blocks are 54 deg +.1 deg and some are 54 deg -.1 deg. you install the timing belt and the cam sprocket teeth line up fine. you are not off 1 tooth which would be noticeable.

than you use the hex adjuster to fine tune the cam alignment marks. and turning the hex will move BOTH cam banks?
so why did they go to a double hex design?
the roller with the 1/2 moon graduated mark is for adjusting tension, not for aligning the cam marks.

my 02 L81 3.0 has a new timing belt cast alum bracket with the 2 new rollers. the 1st design is EB? the 2nd is 01? i cannot make out my cast mark but it looks to be 6B?  but, the previous tech reused the right/lower roller with the fixed middle hub. it is supposed to be the HEX style that you can rotate to adjust the cam timing on cams 3/4. is it imperative that i replace the roller with the correct offset design? maybe thats why the timing went off and bent the valves on this motor? i did order a new offset roller to be safe. $30 no big deal. ebay is great. i did find a local seller with a new timing kit with cast bracket, 3rd roller and belt for $60. maybe i should buy it and resell it for more. they go for $120-150

Question about belt tensioner. It has offset hub so twisting CW/CCW will advance/retard timing. can you adjust timing so it might be before or after timing Mark? My 3/4 cams are dead on. But 1/2 are a smidgen before perfect.
