The bottle trick is where you cut off about 3 cm from the bottom of a 1.25l soft drink bottle, put it upside down over the radiator opening, seal it with some tape & run the engine.
As the coolant heats up it expands & the level rises.
If there are any constant bubbles when the engine reaches...
Checked the spark plugs & they are all at 0.8mm.
All the wiring/leads are fine even tried my spare coil pack but still the same issue.
Did the upside down water bottle trick & sure enough it started blowing small bubbles when really hot.
Took it for a spin around the block & it shuddered &...
Will remove the NGK BKR6E plugs & check the gaps (set at 0.8mm), tightened with torque wrench to 18 lb/ft.
Also noticed that the exhaust note, at idle, is now pulsing a lot more between high & low pressure where before it had a more even note.
Did a comp. test on a warm engine & now its running rough after start up & lacks power.
The ignition & fuel system was disconnected during the process.
All the cylinders were between 135-140 psi.
No excess coolant pressure.
Put in new spark plugs, re-checked timing (10 degrees...
Received a reply from the company stating that they will replace the cam, even though it is out of warranty.
Impressed with their quick communication & understanding.
Should have contacted them in the first place.
Have emailed them to see what they say.
Bought & installed stock 7MGTE cams today & set at 0,0 on the adjustable gears.
Strangely it only pulls 16" vacuum at idle, thought it would be more, and my tune would be all over the place as it was specific to the BC264 cams which had more lift &...
Yes they are Brian Crower 264's, around 7 years old.
Bought when they first came on the market & had the issue with the dizzy/cps being out of sync by around 10 degrees.
Broke as I was doing the final tightening sequence (3rd last bolt), as per repair manual order & torque, whilst adjusting shim sizes :(
(measured shim clearance, removed cam, adjusted some shims & proceeded to re-install cam).
Have used the same procedure on many stock 7M Toyota cams without...
You guys will have to forgive me if I seem cynical/cranky at times but I have my reasons.
Live alone, 54 years of age & have been sick for a long time.
The only enjoyment I get is to take the car for a cruise & beat you young whipper snippers.

My fuelling is controlled by the standalone ecu (Microtech).
Why would altering the position of the crank sensor affect the a/f ratios, that's a new one to me?
Tried setting the CPS to supposedly the right position of 10*BTDC but the engine does not like it.
Have had it dynoed at 5 & 7* and...
Hi everyone, been a while since I last posted a thread.
I have a 7MGTE running a highflow (57 Trim) CT26, aftermarket ECU, using highest ocane fuel readily available.
Have a look at one of my spark plugs (NGK BKR7E) after giving it a blast to 6,000 & 20psi , the highest mappable setting on my...
Never really fully understood how different engine setups are tuned at various ramp rates.
Example: real world (on road) figures-
car A accelerates from 100-130km/h in 4 seconds in 4th gear (1:1)
car B accelerates from 100-130km/h in 6 seconds in 4th gear (1:1)
car A has a large...
