Re: TB removal and then some!!!
Glad I took off the pump....when you go to spin it now....you can hear it "scraping" when turning...sounds like the bearing may be on its way out....
Also plenty of cleaning to do....and that    one quick disconnect pipe on the thermostat housing is still giving me a hard time....I'll get it someday....   20201215_224229.jpg20201215_221707.jpg20201215_221716.jpgSent from my SM-G981U using ZR-1 Net Registry mobile app

Re: TB removal and then some!!!
I had a hard time removing some bolts on another car and everything led me to Kroil penetrating oil. I believe it is a machinists oil and is supposed to be excellent for breaking loose frozen bolts. I did use a mixture of 50/50 acetone and trans fluid before and it did seem to work, but messy..... NAPA sells some pretty expensive stuff made by CRC "Knocker Loose". I think it was the best as all the other fluids I tried didn't help and I left them soaking for days and days.

Re: TB removal and then some!!!
Not having any problem at all with removing bolts....I did notice that the 2 Torx screws on the bottom on the WP which a T30 fits but is slightly loose.... I thought it would be a T35 size.....which I don't have.....so I used the T30 with my ratchet and went slowly.....and they loosen with little effort....
The trouble I am having as mentioned before is with one of the quick disconnect hoses on the thermostat housing.....Phil mentioned to soak....which I have been doing....but not happening right now.....I have another idea to try....so we shall see....

Re: TB removal and then some!!!
Here is what I have been thinking about....since I have the room and I want to remove the housing from the car....is to unbolt the housing and then remove the connector from the housing by rotating the entire housing....this way once the connector is removed...I can get better leverage to remove the hose from the connector.... I am more concerned about damaging the end of the hose....as opposed to the connector....as I have 2 new ones to install if needed....but to replace that hose if I had to...would be a real PIA...20201216_144417.jpg

Re: TB removal and then some!!!
Back working on the 94...more progress being made....with the removal of the oil filter housing... and the thermostat housing out of the way..plus the RS coolant pipe and the EGR tube removed...there is all kinds of room for cleaning and making the LT5 somewhat new again...
Thinking about removing the EGR altogether....has anyone done this??? Will have to check the Forum again for related threads.... The more grease and crud I see...the more I take things apart... As you see in the pics....the thermostat housing is still giving me complications on removing that one hose....I also got 2 out of 3 bolts removed on the thermostat cover...I have the 3rd bolt soaking with PB Blaster on the top and bottom....hopefully that will come out soon... Pic #1...makes it much easier to clean with items out of the way... Pic #2...bolt #3 on the thermostat housing cover soaking in PB Blaster....#1 & #2 bolt came out easily... Pic #3...still giving me a hard time.... can't get the proper position to press down and turn...to release... drastic measures are planned soon...[emoji848][emoji848][emoji849] Pic #4...closeup of the bottom of #3 bolt soaking...hooe that will come out without a problem... Pic #5...oil filter housing gasket material looking real goid...even after 27 years... Pic #6....EGR tube removed....maybe entirely remove the EGR.... 20210119_165848.jpg20210119_170050.jpg20210119_170056.jpg20210119_170104.jpg20210119_170216.jpg20210119_171745.jpg Sent from my SM-G981U using ZR-1 Net Registry mobile app

Re: TB removal and then some!!!
Well when Robert ...posted up in the 3rd bolt soaking pic...on the ZR-1 FB Group....I really got a little worried...because I hate drilling out bolts if I don't have to...so Robert.... I decided to give it another try....this handy little tool took out bolts 1 & 2 yesterday...and just tried again a few minutes ago....but no go with this....in
Pic #1... So it was time to go heavy duty with my corded electric....did little spurts at a time...and still nothing...wasn't about to give up...so after about the 6th try...it happened...the socket started to turn and it spun right out...success.... And Robert was correct....because soaking really didn't do anything....as there wasn't any fluid on the threads when I removed the bolt...so it did not penetrate the bolt at all....I really got very lucky to say the least.... Pic #2... So the thermostat cover is off....and now have to decide if I want to still mess with the disconnect or just leave as is...and cleaning the housing the best I can and replace the thermostat right there... Pic #3... Removing the cover made my day...did not want to wait til later to try....just had it get it done....again...I really lucked out....
