How to set Valve clearence in Mitsubish Lance 1987 Engin model G15B


When Piston 1 is at TDC, (timing points inline), both valves are closed and there should be a gap, say 12 thou on exhaust and 8 thou on inlet. Turn the engine until Piston 2 is at TDC, (both valves closed as with number 1) and adjust, keep going until all pistons have had the clearance set.

What is the tappet settings on a 1200 toyota corolla 1980 model bakkie


It will be the same as for the 1200 on any other Toyota, i.e. Pulsar etc. If you have 10 thou on the intake and 13 thou on the exhaust set while hot, you are withing range.
We used to say a ticking tappet is a happy tappet, so don't try to eliminate all noise from the tappets, just set them so they don't kill all conversation in the cab.

Please give me the correct tappet clearance of intake and exhaust valve of mitsubishi 4g54 with turbocharger


My initial sweep of the web gives Inlet 0.010 thou, Exhaust 0.008 thou.
You would need to check this because industry norm is to have the greater clearance on the exhaust valve because of the increased heat expansion.

Valve Clearance Valve clearance is there to allow the valves to cool in between combustion events (spark), and to make sure the valve closes properly and contains the combustion explosion. You need to cool the valves a little bit, the exhaust valve moreso than the inlet, as it's what sees the most heat as spent burnt gases go past it into the exhaust port. Run too little clearance and you'll cause the valve to "weld" a little bit to its' seat every time it closes, and then take seat metal off again when it opens. Do this enough times and you burn out the valve seat and need the head reconditioned. However, by running less clearance, the valve stays open for that little but longer, and you get more air in and out of the motor, and make more power. Run too much clearance and your motor just sounds like a diesel and loses power and tappet rattle annoys you while you're driving, so it's better to err on the side of caution.
The stock valve clearance (0.008" inlet / 0.012" exhaust, warm) is pretty good for any of the cams I've listed above, they're well-sized street cams, not really wild top heavy race cams that require super high compression to work, so don't be afraid to close the valves up a bit from the suggestions of the cam grinder, which will usually say between 0.010" and 0.014". There are a few ways to set your valve clearances:
Yellow Book Method This is from the factory 3K/4K/5K engine manual, aka The Yellow Books. It's the quick and lazy method.
Set engine to #1 TDC. Crank pulley timing mark should be on 0, distributor rotor should be pointing towards spark plug 1 or 2. Set tappets (counting from the front) 1, 2, 3 and 5. Rotate engine 360 degrees, crank pulley to 0 again, distributor rotor turned 180 degrees. Set tappets 4, 6, 7 and 8.
Nine Method I've never really gotten into doing this, takes too much time and maths for my liking :P Rotate the engine through its' range of movement, as one valve is "on the rock" of its' max lift, subtract the valve number from 9 and that's the tappet you should be setting. For example, if #8 valve is open, set clearance on valve #1. If valve #7 is open, set clearance on #2. And so on.
Stewart uses this method, and rotates the camshaft through its entire base circle and sets the clearance at the highest point. Which is a pretty good idea, as it compensates for the possibility that the base circle has been ground unevenly, and allows you to run the proper valve clearance that you want to run, instead of something that may be a few thou larger in reality.
