What Would You Replace Under The Hood For Restoration

[lonnie]

After years of band aids I am finally going to do it right. I have a '96 with 178K on the clock, bad engine and rusty cooling. I am having a re-manufactured engine put in along with a new cooling system. While they are in there I am going to replace the oil sending unit which had struggled in the past. The mech suggested replacing the engine wiring harness as well.

What else would you suggest that I do "while you are in there" to save me trouble and $ down the road? I want to get it in shape to be a mostly daily driver as well as a weekend adventure vehicle.

Once she is running well I am going to add suspension then restore interior and paint.

Thank you for your input.

Sean

Engine wiring harness should definitely be done. Anything rubber should be replaced and check rear heater hardlines as you can get at them while the engine is out. Could get a rebuilt power steering pump as well.

Following because I will be doing this soon...

Sean, who are you going with for your engine source?

 

[NeverFinis]

Oh, if you have rear seat heating, replace all the lines. They are easier to get to with the engine removed.

kbellve,

I am going with powertrain products. I had wanted to use Jarco, but my mechanic had never used them and had good experiences with powertrain products. I will update as I move forward.

Kernal,

Thank you for the list. This will really help me to guide the restoration. I appreciate your help.

Correction.

Powertrain products doesn't offer remans, for the 80 anymore. We are going to try to get one from Jarco.

Be aware, remanned engines are generally a only parts replaced out of spec and replaced with cheap Chinese parts rebuild.

Cheers

Thanks Ian.

Is there someone that you would recommend that is better than most?

Thanks!

New Toyota short blocks are still available.

That is what I recommend with a rebuild on your head.

What is wrong with the engine at 170K? Head gasket I would understand, but what is wrong with the short block?

Jarco only uses Toyota parts in their rebuilds (via direct communication). You cannot order direct. Only via dealership or your repair shop. Lead time was the only issue when Jarco was considered for my vehicle. Lead time was 6-8 weeks at least when I contacted them in August 2020.

Long story that is documented on this forum from back in 2007. I blew the rear seal when I was in the middle of nowhere TX, no phone. I tried to limp in and the engine blew. It was my DD so I had to get something done, but I was short of cash. I found a guy who would put in a recycled engine on the cheap and I got what I paid for. Engine has a bunch of issues and a ton of rust. I just want a new start and make up for the errors of my youth.

Lead time is less of a concern than getting a quality product. What did you wind up doing? How did it work out for you?

Thanks.

Still have your old blown engine? I’d seriously recommend rebuilding a good running engine vs a reman.

Unfortunately I don't.

Out of curiosity who / which shop are you having do the work?
