SO! 1.6 N/a..... Should i have to worry about EGT's? like without a turbo they aren't really a problem are they?
i really have no clue... have never owned or driven a diesel.. hoping to swap in one to my 84 jetta soon though.
Hello to a fellow Orillia member!
EGTs are definitely a concern with any engine, turbo or not. If anything, EGTs would be more of a concern with a NA engine as less air + more fuel generally = higher EGTs. Intake air plays a vital role in cooling the diesel engine. That said, if you keep your fuel settings stock you won't have a problem. You're going to want to get a pyrometer installed before you start tweaking that screw though.
When you have the engine out is the perfect time to drill and tap the manifold.... much much harder with the engine in the car.
If you're leaving the pump stock you probably don't have much to worry about... but most people don't leave the pump stock for long. :wink:

Good thought. Even if you don't want to install a pyrometer setup now, you could always drill and tap the manifold with the engine out and put a pipe plug in it for now.
at least when drilling you don't have to worry about shavings going into the turbo... you could probably just drill the manifold while the engine is on. best of all the manifold will be warm so less likely to crack or something...
i've seen a toyota truck with a nice burnt motor... the cyl pressures got progressively worse until about 50-80 was read from the worst cyl... the manifold is setup so that the cyl with worst compression receives exhaust gases from all other 3 cylinders... the best cylinder does not have any flow from other cylinders. just goes to show that crappy exhaust manifolds don't do the motor justice, and that EGT's are a definite concern as this motor was non turbo. always make sure to install the pyrometer where all of the exhaust gas meets, otherwise you're not getting the full picture.
ok so what would you guys suggest i use as a low budget temp guage for exhaust gases?
