Is there a way to check that injector flow?

What's to look at on the injector?

The kick down switch seems to working okay when the pedal is full down. I wonder if removing that restrictor would allow it to kick down with less than full throttle. It seems as though right now it takes an awful lot of vacuum to kick it down. BTW, what kind of trailer do you pull with your Loyale?

While checking all the vacuum lines on the 93 Loyal, I pulled the vacuum line to the transmission regulator?, if that is what it is. Any way, there is a restrictor in that vacuum line. It looks like it reduces the diameter of the line down to about 1mm, and is made of bronze. Is that restrictor required? m It does shift up pretty early and hard to kick down.

Not running hot. Barely at a quarter off cold. Thing is, it did not ping before head gasket and timing belt job. Is there some way to physically check the piston on number 2 or 4 cylinder at TDC against the timing marks on the flywheel?

The timing now is at 18. That is as far as I can go without pinging. Done all the other stuff, new everything ignition wise.. all NGK Been thru 3 tanks of gas, Sea Foam, each tank., I always run 89 or higher as that is what the jobber I buy from gets and no alcohol in his gas. Compressions good. I can't help but think that left side cam is off one notch on the belt. But which way? When I got it back from the shop that did the head gasket, and timing belts, I checked the disty timing. It showed at 23, but it had not pinged before, and I could tell looking at the disty, that it had been at that place forever. I am thinking if that left cam were off one notch, it would have thrown off the disty timing my about 3 degrees, but I don't know for certain.

Still struggling with getting this 93 Loyale to stop pinging. The sticker under the hood says to connect the Green 2 pole connector when setting the ignition timing. My green connector has only one pole. There is another one pole connector that is white. It does not seem to make any difference whether one, both, or neither is plugged in when I set the timing- it does not change. What is it supposed to do, and which ones are really supposed to be hooked up?

What difference is this supposed to make? I did mine both ways and it made no difference, on a 93 Loyale.

The shop that did the job pulled the front end off and re-checked the belt timing. Before they buttoned it up, they called for me to come see it. It was correct. I guess the angle I was looking at the pulley made it look off to me. But here is the thing. It was still pinging. I picked it up this evening and no more pinging but man, is it doggy. Yep, you guessed it. They just retarded the timing to 17-18 degrees! After I saw that, I decided to check a few more things. Compression on all cylinders was 174, 170, 173, 165. ( 1 thru 4) Cylinder head temps with the engine warmed up and running at idle are 172, 158, 177, 146 F. I have not tried to do a leak down check yet, as I don't have a good regulator set up. I am wondering... is there more than one way to install the pulley on the camshaft? If so, does it affect the cam timing? I cannot think of any reason why all of a sudden the temps on the left bank of cylinders is low and the lower power and pinging.....

Pulled the left ( drivers) side cover. With the three III hash marks on the flywheel lined up with the little index on the bell housing, the mark on the cam gear is not at 12 O'clock. It is off maybe about 4 or 5 degrees toward the fender. This might explain why the distributor timing was indicating at 23 BTC instead of 20. The distributor is geared to the left side cam isn't it? This should also explain why the left bank is running 40 degrees colder than the right. Anyway, I took it back to the shop that did all the work. The shop writer is a jerk and is disbelieving that the cam timing could be off. They have not looked at it yet. Now, I am wondering... I drove it that way for about 300 miles. Could it have burned and exhaust valve that way?

How much, if any rotational play is okay?

I'll look at that tomorrow. I thought access would be restricted by the compressor, and alternator.

I am curious about this. When you say "free play" in the shaft, do you mean side to side or rotational?

Hi, New on this forum and new to Subies. Have a recently acquired 93 Loyale with 76K on the meter. It had a major oil leak on the right head gasket, so I had it changed along with timing belts, pulleys, tensioner, etc. The compressions were like new. I now have preignition pinging on the left bank only. Resete the timing to 20 BTDC, new plugs, rotor , cap, good fuel.... It put an IR thermometer on both side exhaust down pipes and the left side in about 40 degrees cooler than the left.. I am stumped. It is not making any noise- like knocking or lash adjuster stuck. It runs okay, but not very smooth accelerating, and slightly rough idle when warm. If the belt on the left bank were off one notch, could it cause this, or would it run really lousy? Thanks.
