Interference Motors

[arjan]

3.0 & 3.4 non interference,
2.4 (22RE) & 2.7 interference.

V8 engines I have to go by what's posted above.

[4runnerchevy]

3.5 2GR-FE V6, is it interference ?

This is gonna end up being searched someday!

I am guessing this one is, cause of the VVTi. I really didn't know there were this many Toy motors.

[YotaFun]

Wikepedia Toyota Engines.
It state every toyota gas and diesel engine, now its just a matter of researching each individula motor to see.

[DHC6twinotter]

Yeah, that's my guess as well. I was trying to find info on all the GR series motors last night, but gave up after a bit. I'll try to work on it more later.

It does seem that many of Toyota's VVTi motors are interference. Interesting.

Doing this from my blackberry so I hope it works!

Copied over from Wikepedia:
Toyota Motor Corporation has produced a wide variety of automobile engines. The company follows a simple naming system for their modern engines: 1. The first numeric characters specify the engine block's generation 2. The next one or two letters specify the engine family 3.
The suffix (separated by a dash) specifies the features of the engine:
Suffix Feature A Valvematic variable lift intake head
B Twin SU-style side-draft carburetors
C Carburated / California Emissions Controlled
D Twin Downdraft carburetors
E Electronic Fuel injection
F Economy narrow-angle valve DOHC
G Performance wide-angle valve DOHC
H High compression like 9.8:1 (example: 5E-FHE)High pressure charged (example: 2L-THE)
I Single-point fuel injection
J Autochoke (Early models) or unknown pollution control
L Transverse
M Philippines' market (meaning unknown)
N CNG fuel
P LPG fuel
R Low Compression (For 87 and below octane fuel)
S Swirl intake (1980s)
SE Direct injection (1990s)
T Turbocharged
U With Catalytic converter Japan-spec emissions
V Common Rail Diesel Injection (D-4D)
X Atkinson cycle (typically also indicates a Hybrid engine, as Toyota only uses the Atkinson cycle with hybrids)
Z Supercharged

For Example•
4A-GE 4 - 4th Generation Engine In The A Engine FamilyA - The Engine Family it is inG - Wide-angle dual camshaftE - Electronically Fuel Injected•

22R-TEC 22 - 22nd Generation Engine In The R Engine FamilyR - The Engine Family it is inT - TurbochargedE - Electronically Fuel InjectedC - California Emission Controlled• Note: Toyota, in 1987, began assigning dual letter engine codes to some of the "engine family" categories in some engine lines, particularly six cylinder models. This can create potential confusion.

Eg. 1UZ-FE - This is not a supercharged, narrow angle, fuel injected U-series engine, but a narrow angle, fuel injected UZ-series engine. Confusion is easiest to avoid when using the dash to separate between the engine series and its own characteristics: for instance,
1UZ-FE rather than 1U-ZFE

Err...that sorta worked Avy. There is some good info there. I never realized toyota made 2,3, and 5 cylinder engines.

BTW, you hit 1000 posts.

[YotaFun]

fixed it a little....

[Tankota]

Wow that has to be the longest post I've ever seen, haha. Some good info there though.

Chevy - Did you break a timing belt or something?

[DHC6twinotter]

It appears that the GR series motors are interference.

I also ran across several posts on various forums with people claiming that all VVTi motors are intereference. This seems consistant with what we've found so far.

Also, the VVTi versions of the 1MZ motors were interference, so I'll go back on edit one of my previous posts.

Currently trying to find info on the UR sereis.

[YotaFun]

this is correct I believe all VVTI motors are interference.
I can't remember if it is the 2ZZ or what that is in the Celica, but I know that if the chain goes, say good bye to your valve train...

keep the search going dan!
