GT500 Oil Injection lines

Post by TrevorGT500 »

I found today a pool of injection oil sitting on top engine case, I assume the oil lines are cracked somewhere. Does anyone know of a company that can repairs or supply replacement lines ?. Any help appreciated.


Thanks Trevor

An easy way is to find the leak and cut the pipe there.
Either use compression type pipe fittings to repair it or even sleeve the cut with some plastic pipe glued in place.
If it's a joint that leaks, try clear nail varnish to 'paint' the leak after cleaning it with thinners.
Washers can just be replaced but care not to overtighten.
Think of how stupid the average person is, then realise that half of them are more stupid than that.

You can sometimes find oil lines on e-bay. I got new ones for my T-350 a while back, but they were expensive. What the other guys say will work.

Two likely sources of the leak: the banjo bolt washers & the oil line junction block.

We probably shouldn’t be surprised that some of the plastic oil line washers are leaking after 40 years.
Suzuki doesn’t sell them anymore, but sells aluminum washers instead.
Has been my experience that Stat-O-Seal washers are a much better choice.
They are reasonable $$$ & are available from McMaster:

The oil line junction block (one line in & two lines out) can develop leaks on the two-line side.
Cleaning & sealing this area can be pretty effective.
A few members have done this with good results.
We’ve used a variety of products — I’ve used Clear Electrical Tape.

As Alan warned, take care on tightening the banjo bolts.
(I’ve seen a torque spec for them — its something like 1 ft-lb.)
