Well i received new Glow Plugs today , My Car had THE FOLLOWING ISSUES
No Glow Plug Light and was very hard to start; i received some great info from Forum Members ( Thank You ) So in replacing Glow Plugs i learned a couple of things USE RATCHETING WRENCHES !!!!!! I have regular Open End / Box End wrenches and it was harder than needed to be to remove the nut that holds the wire to the Glow Plug and definitely very hard to remove Glow Plugs , Some tight spaces there ! When i first acquired my Car it would literally start instantly , After a while out of the blue, it was harder to start , it took a few more cranks than usual to start and a couple of weeks ago the Glow Plug light did not come on and it took about 15 + seconds to start along with unusual smoke as it started . Well i changed glow plugs today and it starts just like when i got it and the glow Plug Light comes on again , in hindsight now i know why it gradually became harder to start, the Glow Plugs were failing one by one until all of them were shot . In all honesty i changed 3 out of the 4 Plugs the third one as you see them from the front of the car is very hard to get to and will have Onager replace it when i take it to have the Oil Temp Fuel Gage swapped SHOUT out i need and Oil , Temp Fuel gage from an 81 or 82 anyone ? So there You go Lessons learned !
