I can't find any info on it, which is in my newly bought Blazer. Doing a full tune up on this thing, and can't find some stuff I need to know, like where the PCV valve is located, hahaha. I feel kinda dumb, but I haven't touched anything this old in 3 years. Can anyone steer me in the right direction?

Vehicle info might help. And what you want to know might help also. You say you need to know some stuff but only ask about the PCV valve. Is that all you need to know?

 

ive also never even herd of a 4cyl 4x4 blazer... i wish mine was a 4banger.. are u sure it not a 2.8 v6?

 

The 2.5L was used from '85-'87. For more info on the history of our trucks, try Wikipedia's listing.

 

actually the 2.5l iron duke was used right up to 93ish i believe in the 2wd s15s and s10 trucks until they went to the 2.2 like the garbage cavaliers
but my point is blazer/jimmy 4x4 did not have the 2.5/
it just sounds like if the blazer has the 2.5 in it, its a 2wd,
for more information about our real trucks try wikipedia's 4x4 blazers
so i decided to take a search, and found that. 85-87 they did have the 4banger 2 wheeldrive blazers. not 4x4
even thought you can take the bellhousing from the 2.8 v6 and bolt a 2.5 L on it, it is possible to make a 4banger 4x4 blazer.

Mine is a '87 2 door Blazer, Iron Duke, 4x4, for realz, yo. But seriously, it is. Now, I don't know if it came like this or what, but it's got the Duke, and it has working 4x4. In the meantime after posting this thread, I did find another forum dedicated to the iron duke which has a dude who has 1.4 million miles on his, lol. But yeah, maybe I have some super rare combo, or maybe it was swapped. And I also found out where the PCV valve is, which is in a terrible spot.

 

well i want one! i never ever thought that that was for real in the 4x4 blazer! i always wanted to do the swap, but i hate dealing with wires.
i think i mayyy have found a new project. 4x4 5speed ironduke blazer
get your vin number, and see what it pulls up for what it came with i wonder if it depended on where they were made(like if it was in usa, mexico or canada, cause i have never ever even herd of one befor in canada

btw i wanted to ask. how well does the 4x4 work, and do you got pictures of yours?

 

Well, the lady I bought it from said it works awesome, but I haven't had a chance to take it off road to test it out. It snowed a tiny bit last night, and I need to get a 30 and mob it a little in the next few days. It's a 4 speed, though. Really wish it was a 5 speed. My dads old S10 truck with a Duke and a 5 speed shifted way better.







Bought it for a snow car as I can't drive this through the snow (my DD up until I bought this Blazer)
