Power Steering Problem

[Bill Vun]

Hi

I'm a newbie to posting threads at this site but I've been reading threads for a long time.

I have a 1989 (build date) Supra, which I just got repaired for a blown head gasket. They machined the head and relaced the head gasket and I've had no problems with that.

My problem is that I'm finding my steering has become a lot heavier than before I put it in for repair. I have asked the repairer if they have modified the power steering however they said they haven't touched it.

I have checked the power steering fluid levels as well as have a basic look at the power steering lines to see if anything is leaking but all seems to be fine.

Not sure where else to look and would be interested in any possible thoughts or soultions to my problem.

Thanks in advance

Regards,
Bill

P.S I have owned the car since brand new and this is the only major problem I have had with it apart from a few battery problems.
