B Engine Glow Plug conundrum...

[pipaguapique]

Hey everyone!

Need help with this issue i just came across. I'd would love to put all new glow plugs on my 40...but...
I wend to remove them to find out what they were, but it turnes out it has 2 different kinds:
PT 94's (outside) and PT 101's (middle)
PT94's is 19V and PT 101's are 20.5V. Is this correct? Or the PO just mixed them up? I read this thread and it looks like I should have all PT 109's (19850-68040)

any advice?

Thx
Jerry

I'm not familiar enough with your engine to say which plugs are correct, but I have never heard of using different plugs on different cylinders. They should all be the same.

anyone know the difference between PT 101 and PT 109?

anyone know the difference between PT 101 and PT 109?

A check of the HKT specifications for both plugs appears to show they are identical.
