Supra MA70 powersteering

Hey Guys,
I started my Supra ma70 up after letting it sit idle for 3 weeks. The power steering pump was whining badly and the steering was laboured and shuddery. I had a spare pump from an import engine, and with a bit of parts juggling between pumps I fitted the other pump. On start up the same whine is heard and the steering has not changed at all. What do you reckon it might be...a blockage in the steering rack, maybe? Thanks in advance dudes.

Check for air leaks in the system, and yes blockages anywhere in the system can also cause those symptoms. I had a similar thing happen recently when one of the hoses got a pinhole leak and started drawing air in; you'll know this is happening if you see little bubbles rising up in the fluid reservoir when the engine is running.

Thanks Norbie,
that sounds like it could be the problem. Cheers.

I'm getting bubbles in the reseviour so like you said Norbie, its an air leak. I tried pump-bottle spraying some water on the hoses and connections to hopefully hear when the hole blocked with water, but had no luck. Is there any other way to locate the air leak, or should I take it to some front end people? Thanks.

When you changed the lines, did you bleed the system? This can take up to 15 minutes or longer to do properly.
If it's on the high pressure side it will leak fluid and will be obvious. Recheck all the hose clamps and if any look sus, replace them.
