hey yall, new to the site looks pretty good hoping to get some good tips here. i have a 89 k-5 kblazer with 89,xxx on it. has the 5.7 with the 350 turbo i believe, could be the 700 though. anywho its gonna be a mud truck and this is the first weekend its going. its all original stock just need some tips to keep it from blowing up or breakng. like and vacumn or breather holes that need to be capped or taped. any electrical that should be souldered and heat shrinked.......any possible help would be appreciated. thanks hope to be hearing from yall soon.

 

we used to take our 91 out all the time...She never had any problems. We used to put dielectric grease on all the electrical connections, spark plugs...all that. Do NOT wrap your breather lines. They are there for a reason. If I am correct there is one on the rear diff, up under the rear somewhere. Ours was not too far from the rear diff. There's one on the trans. And there is one on the front diff. That one is right by your headlight somewhere. Extend them. That is the best thing you can do. Route them up high...a lot of people route them to the firewall or into a snorkel. We never re-routed ours because where we went it wasn't a big deal. It had a 4 inch lift on it so everything was raised already. Other than that a snorkel is a good investment. I do have a build on this site if you want to go by that from our blazer :-) Otherwise the blazer kicks butt for offroading...at least ours did :-)
