Re: Swapping Control Arms for a little more Negative Camber

Best bet is to try it and as your car is lower you may find that one of the bump steer adjuster kits would work to dial out any bump steer. As my car is slightly higher than standard I need raise the steering balljoint and none of the available kits appear to allow for this. Remember that adding cas...

Re: Swapping Control Arms for a little more Negative Camber

I have adjustable LCA's and from memory 10mm does add about 1°negative camber. Two things to consider, one is obvious and that is to make sure you have enough thread adjustment on your steering tie rod ends. The other less obvious, make sure the alignment includes the caster setting. Lengthening the...

Re: Engine lost compression

If 16°is maximum ignition timing advance you might want to check camshaft timing, you will probably find that the inlet camshaft is too far advanced.

Re: Brake line leak on hardline @ prop valve

Could be vibration if the brake line is long and not supported anywhere close to the connection.
If there is no evidence of corrosion near the connection you could try tightening the nut.

Samco can supply a 'T' hose that would work fine and to keep it securely in place you could use two Mikalor screw clamps.

Re: rear tire skipping under hard braking

So last night I jacked up the front of my car and turned the front wheels by hand and one side had noticeable drag and this was caused by the brake piston not returning correctly.
The OP might want to try the same test before doing all the other stuff stated above !

Re: rear tire skipping under hard braking

A blown damper would show the particular corner effected 'dipping' under hard braking, especially at the front. Under hard cornering the car would feel different when turning different directions. The best test is to do as suggested above, soften the settings but do one damper at a time. 3.5° is a l...

If you suspect a side to side brake imbalance always check the non-working side, the side that it veers away from. Just to make sure I got this correct in my head. If i car turns to the left under braking, then I need to check the passenger side? Yes, I can lock the brakes in straight line hard bra...

Re: rear tire skipping under hard braking

What happens under hard straight line braking: Steering pull ? Wheel locking? Front diving ? There are so many things that could make this happen, taking the steering out of the equation may help to diagnose the problem earlier. Negative camber has a big effect on braking, reducing braking grip when...

Re: AE86 16V - How to set ignition timing...

The timing is locked so there is no fluctuation thus making setting it easier and more accurate.
There may also be a 'failsafe' in as much as any error codes would show before the timing is set.

Re: Rear axle retaining nuts

Yup, yup. Thanks sham. Do you know why the factory nuts have that extended flange/lip? Clamping force and also related to 'hardness' of the fastener, ordinary flat washers cannot exert the same force as hardened steel washers. Toyota do stuff right, that's how they roll.

Self locking is achieved with controlled deformation of part of the thread.
Interestingly they may not be available in the USA

Ok I just read through the whole thread again, firstly turning the distributor clockwise retards the timing and putting the engine in diagnostic mode further retards the timing and that would explain why the engine dies when you put it into diagnostic mode.

When you say harder and harder to start can you describe what is happening ?
Does it turn over really slowly as if the battery is flat.. but it isn't ?
Or does it turn over at the same speed but refuse to fire ?

Re: Ignition timing problem

I suggest that you try advancing the ignition timing. What you currently have is a spark that is happening somewhere around 0° but you need a spark that is happening at 16° before 0° (16°BTDC)

Re: Ignition timing problem

Also make sure that the camshaft dimple notch thing is lined up when looking through the oil filler hole. See factory service manual.
I can't remember, maybe someone will, is the camshaft dimple lined up when the engine is on TDC compression ?

Re: Ignition timing problem

First you need to ensure that your distributor is installed correctly and not a tooth out. The way that I do this is to set the engine with cylinder number one piston at 10°btdc on the compression stroke (or where you want the spark to happen) remove the distributor cap and check that the rotor arm ...
