2LT Turbo lag... related to cracked radiator??

[Turby2LT]

Hi gang.

Over the weekend just gone, I noticed two things:

1. Turbo lag... it usually kicks in around 2000rpm, but nowadays it's not kicking in until well over 2000, approaching 2500, just about where peak torque is. But only slightly noticeable in terms of performance.

2. The radiator sprung its patched leak again. Coolant being relieved via the reserve hose, and the whole cooling setup bubbling away. The temp gauge was at redline for a bit.

Now someone's mentioned elsewhere here that excessive white smoke from the exhaust could signal a cracked head and leaking coolant... there was quite a bit of white smoke at startup, but then again, The Beast had not been started for a couple days and it's been cold overnight here in Melbourne.

Any thoughts?

Thanks in advance...

Might be a sign that general engine condition is poor. Best to get it comp tested and go from there.

Check your vacuum hoses, if these are cracked or perished you will 'loose' the turbo on the Surfs. Sometimes the Engine just looses power, as there is a leak in the system, and no boost is being made.

As for the cracked radiator.. excess pressure from a cracked head? Wouldn't be the first time in a 2L-T

The white smoke is coming out of mine atm, in my case it is a rear turbo seal. This could also be your problem, wipe your finger in the exhaust and see if there is oil there.

White smoke on start up can also be the glow plugs not working properly.
