If you still haven't figured it out i had a vacuum leak that made my 94 ka24e idle at about 250 and if I revved it to about 1000 and back down it'd cut out. Could be the same thing.

Hello everyone! Bit of an update for you guys, Shingles is gone and I have compression tested the engine, though, not as satisfying as I hoped.

Lets start out with the right side of the engine, bank 1 in most vehicles, and list them cylinders 1, 2, and 3 on bank 1 to eliminate any confusion, bank 2 is the left side of the engine cylinders 1, 2, and 3, for the left side. this is of course using the proper left and right terms for working on engines, so from the perspective as if you where sitting in the drivers seat.

bank one, cylinder 1, compression at 100 psi, cylinder 2, 100 psi, cylinder 3 100 psi.

looking good so far.

bank two, cylinder 1, compression at 90 psi, cylinder 2, compression on 90 psi.

at this point I was certain the timing was off, on to bank two, cylinder 3, compression at 110 psi.

well that's disappointing, not sure which cylinders are companion cylinders with out looking it up, didn't matter much to me though at this point because it looks like I have 2 weak cylinders, one strong one, and 3 that are getting worn.

At this point I have decided to pull the motor, tear it down, and inspect it.

I have several options at this point, re-ring and re-bearing, send it to a machine shop for boring and resizing, or finding a good used motor.

there is a jdm place in Washington that ships to Alaska, gave me a good price on a motor around a grand. This store advertises motors sent over from japan with only 50,000 miles or so on them, ready to go and be dropped in to a vehicle.

getting the lower end rebuilt at a shop may only cost 2/3 to 3/4 of the price of the new used motor, but I would still need to look at the cylinder heads, and rebuild them.

there is a running junkyard motor, they claim all the cylinders are tested at 110 psi, but my coworker does not trust them, plus the motor is out of a vehicle that is showing high millage with no history on the motor.

I have done a re-ring, and bearing swap on my ka24e hardbody, the engine works good, other than a lifter making noise, but that's napas fault for getting me a crappy refurbished head, ill fix it eventually. but for the vg30e im not sure what will have to be done with the heads after I get them off and looked at. I could lap the valves and hope guides are good.

anyways, that's my update for now, any suggestions from you guys?

Getting my JDM VG33e engine into my truck took some time, like 3 or 4 months getting all of the parts together. Most of that time was because "a-hunting-I-did-go" to find the accessories and the brackets to bolt them to my engine. The JDM guys never seem to know what the engine comes out of, since they do not have that information and all they are selling the engine for is the long block assembly.

What I got was a Pathfinder engine - same as Deerhurst. There must be a lot more of those in Japan than there are Frontier and Xterra vehicles.

Getting all of the accessories and brackets almost doubled what I paid for the engine. Not all of the parts were expensive, but shipping each one was at least $50.

If you can get your JDM place in Washington to get you a 3.3L engine out of a Frontier or Xterra, it is worth it to pay extra.

Also, most places that sell engines know when they have one engine that is better than another, and they price them accordingly. The first engine Deerhurst got was an old rust-bucket that looked like it had been used as a boat anchor for the last 10 years.

As for getting the VG30 rebuilt: I heard reports that it was going to cost a little more to have it rebuilt as I was looking to pay for the JDM.

As for a junk-yard motor: There were high mileage VG33 engines here, too. I, personally, didn't want to do all that motor swap work just to have another old engine between my front fenders.

IPL paid more for that boat anchor too. I went with a place out of San Diego.



Not sure why it cost JP so much to swap it to XTerra spec. I snagged the brackets from a junk yard X for $45 for both of them. Used the old stuff for the core deposit on new PS and alternator.



I think JP and I both have good threads on what it took. Worth the read if you might want to go that way.



A new VG30 near me was easily 3x the cost of my JDM motor.

A local pick-n-pull had a single Frontier to get parts from, but it had been picked over for a really long time. Nothing was there.

All of the parts I got came from eBay, and all of them came from individual sales.

The accessories were easy to find. The brackets took work.

Here's my thread:

Oh yeah. I had no problem dumping money into mine.

Still, it was a little shocking how much was going into it.

I am not sold on the whole switching to a 3.3 liter, seems like a bit of extra work, I can look in to it though. at this point I just want to get the silver hardbody in working order.

I think I will be listing my red ka24e hard body for sale this weekend, perhaps I will get enough money that I can quickly do a rebuild on this silver one. I hate to get rid of one but I simply don't need two trucks right now. and im having a heck of a time trying to sell my van, just not a lot of intrest in it right now. Ah, the issues with needing cash lol.

I don't think slightly low compression would cause the engine to run at 250 RPM.

Gummed up valves would cause low compression, though.

Can you run a treatment or 2 of Sea Foam through it?
