1986 Porsche 944

MOTOR VIBRATION........

Good day to everyone.

I bought a 944 with high miles 149k.

The good:
Motor seems strong.
Shifts good.
Breaks good.
Electrics and charging system good.
Suspension tight.
Great oil pressure 40-50 lbs.

The bad:
Motor was noisy.
Motor front seal leaked.
Balance shaft seals leaked.

Repairs that I did:
Motor noisy: replaced the timing belt and balance shaft belt; tension set without a tension gauge, motor quite now.
Motor front seal: replaced
Balance shaft seals: replaced
Set timing for motor and balance shaft per Clark's repair manual online

The motor is noisy when idling (vibration)

Could this be motor mounts?
What do you think?

Jim

PS. Should I have used the directional seals for the balance shafts?
