| 1 | Yes you can. Customers still think that eliminating an oil burning engine has to be an expensive engine repair. Completed in one day at less than half the cost of a valve job. Even on the transverse mounted V6 you can install the valve seals easily. Remove the body from the handle to remove springs in tight spots. |
| 2 | List is too long to put here, but will work on all valves with standard springs up to 8MM stem diameter with one keeper groove in the stem. |
| 3 | Yes. We've had 100% success rate. |
| 4 | NO! In
fact most of the time you should just clean the valves, replace the seals, put all the valves and lifters back in
their respective positions and
your done. Late model valve trains rarely wear out. When you take into consideration better materials,
better lubrication, better fuel systems, better fuels and lighter valve
trains. You can see why these valves, seats and guides are lasting
so much longer. The weak link is the valve seal. |
| 5 | Yes, absolutely. I have been doing them on Toyota & Lexus myself for years. Decarbon the valves, replace the seals |
| 6 | Well, I personally having done valve jobs on Toyotas for the last 20 years and have never encountered this situation. Lower ends are not wearing out like they used too, for all the same reasons the valves aren't. Engines now all have low tension piston rings and much better material compatibility. |
