Re: Heater Core Flow

The water valve on the 2.3 heater core is internal to the core. The valve controls the amount of water flowing through the core & is adjusted by a lever on the dash. Your valve is defective, those plastic parts that fell out were it. IF it's fully open & you can no longer shut it down there ...

Re: rear wheel bearing/parts

First off the "M75" on the option plate is the transmission, not the differential as you state. A M75 tranny is a MSG-5, which means you have an Isuzu 10-bolt rear & a 2.3L engine since you also have a VIN starting with "4JA1". This is important because rear axle assembly par...

Re: Stock air filter adapter for Weber 32/36?

http://www.carburetion.com/Products/ProductDetails.aspx?Part=99010.675 See if this might work, #99010.301 has a taller lip if your air cleaner clamps around the lip like a Chevy LUV. If not Redline makes similar adapters for several different Weber to stock air filters but nothing specifically for a...

Re: 270 Camshaft

Assuming you have all the emissions deleted you can run more initial advance than the stock, probably in the range of 12 degrees. Get the engine running as well as you can, gradually advance until it starts to knock under load, then back off until it quits, then check with a light to see what it is ...

Re: Running rich

Sounds like your float level may need adjusted. Some 2.3 carbs have a float bowl fuel level sight gauge on the front of the carb, if yours does the fuel level should be centered on the circle in the sight gauge. adjust by bending the stop tab on the float. Also make sure the fuel return from the mec...

Re: 270 Camshaft

The 38/38 carb may not be too much depending upon how you drive but it is designed more for a racing application than a daily driver. The 38/38 carb is like two one-barrel carbs synchronized to operate together, both start to open at the same time & dump a lot of fuel early (this may be your hes...

Re: 270 Camshaft

Valve adjustment is what it says on the box the cam came in, there should be a label with the cam specs. If there is no label call Delta & they can give you the info over the phone, I've had to do this before when they failed to attach the cam specs label. .006 intake, .008 exhaust is what the c...

Re: Auto Front Hubs (87 4x4)

Pull one of the hubs, see if the axle is 17 or 24 spline, then get manual hubs of the same spline count.

Re: Carb swap

I would say yes, with the right modifications: the linkage may not be exactly the same but he correct linkage will likely fit the swapped carb; the electronic connectors may be different, figure out the function of each wire, then splice on the correct connector(s).

Re: 2.3L Rebuild Pistons and Crank Question

NO to all you asked. -.040"/1mm is the maximum overbore for the 2.3 block. Anything more & you risk boring into the water jackets. The 2.6 is a larger version of the 2.3, internal parts don't interchange, external parts usually will. You can't use 2.6 pistons on a 2.3 crank(the block won't ...

Re: 2.3L Rebuild

Either matching valve seats or grind out the existing, ask your machinist. You'll likely need either a set of valve lash caps or elephant or swivel foot adjusters to correct the rocker arm to valve stem tip contact with the reground cam. The latter two need installed before the rocker shafts, the ca...

Re: 2.3L Rebuild

http://www.isuzupup.com/viewtopic.php?f=18&t=25450 See this problem with a Pacesetter header. I think the problem is the 70-1105 header is designed for the old square port 1.8 & 1.9 engines but since Pacesetter switched to a round port flange it will also fit a 2.3 head, but I think one of t...

Re: Amigo differential question

My Trooper has the same tranny OD & differential gear ratios but has 31-10.50x15 tires (actually 30.5" in diameter) & runs about 2800-2900rpms at 65mph. A 26" tire will turn at least 3250rpms at 65mph, probably a bit more because of the actual loaded radius. RPMs & MPH for a gi...

Re: Amigo differential question

That's probably a ABS tone ring & the ABS sensor you're looking at. As long as the added parts don't make the assembly too large to physically fit into the Trooper axle housing (and I don't think they will) the Amigo 3rd should work in the Trooper axle, the rear ABS just won't function. The down...
