IH8MUD · Almill13 · 10 Nov 2026

After two years of ownership it is time to dig in and give Olga a refresh. A couple weeks ago she started to run poorly and missing at idle. After checking all the basics timing, fuel and spark to no avail I did a compression check and found two of the cylinders are dead. My plan is to take the head off and get it rebuilt and hopefully that is all she needs to get back on the road. While the head is off I'd like to do some other small upgrades and basic maintenance. In the past year I've... Read more

Hi everyone! I’m new to the forum and wanted to introduce myself. We’ve owned our Salsa Red Pearl 2008 Land Cruiser since new, and it now has approximately 217,000 miles. It’s Southern-owned, unmodified, and has been a wonderful vehicle for our family. Recent maintenance includes a new radiator and spark plugs, along with a newer $1,500 set of Michelin tires with approximately 10,000 miles on them. We’re preparing to sell it and would love to see it go to someone who appreciates Land... Read more

I don't like being beaten by any piece of mechanical apparatus, but I am completely out of ideas. Condition: 3fe in FJ62 running rich ( light gray smoke with occasional black puff) in open loop and closed loop after the following: *Head gasket replacement (compression in the coolant). *New ignitor (random missing then total failure) *Refurb OEM fuel injectors and pigtails *New ECT sensor *New TPS (old one was sticky and would not mechanically return on its own) *New spark plugs (multiple...

Hello forum! Been putting a 1992 Volvo 740 Turbo back on the road. Had it working pretty good, got inspected, then while at local Aldi's...died. No start, then just cranking. Towed home and been going through the old girl. Here's what I got: getting fuel and air (new main pump and filter - smells like gas after cranking a bit) spark plug light on a plug between wire and plug doesnt light when cranked. The Tach does not move when cranking. Tested CPS at 178Ohms at the coil and .24V AC while... Read more

Hey guys Looking for some fast info Importing a 12HT and h55 (engine and trans only) from the Netherlands ... I’m filling in the US EPA form and want to make sure I tick (literally) all the correct boxes. Has anyone done this before? The form isn’t clear. The definition on the decision flow chart seems to classify the diesel under a “marine, locomotive, or other land-based nonroad” vehicle as it is not a “spark-ignition engine” So would it be box “B” for locomotive engines, or...

I read somewhere (maybe Slant.org) that when using HEI, the plug gap should be opened up. My setup - 273/235 with Chrysler Electronic distributor and 4 pin HEI. Anyone know, maybe @slantsixdan I edited the thread. - not using the Chrysler electronic ignition, just the distributor and HEI module

on friday, i started mt '84 fj60, let it warm up a bit like normal, then pushed the choke in and started driving my son to school. when i got to the end of the street and stopped at the stopped sign, the truck slowly stalled. it wouldn't restart, and still won't today (monday). i towed the fj60 back home with my other truck and started diagnosing. checked spark on wire one (using a spare spark plug) - have spark. checked the fuel level in the carb bowl - it's either completely...

New 80‑series owner here. I just got my first 96 Land Cruiser, and I’ve been wanting an 80 for a long time. The truck is in good condition overall, except for the high RPM at idle. Here’s what I’ve done so far: cleaned the MAF, checked the air intake for cracks, replaced the spark plugs, verified that both O2 sensors appear to be functioning properly, and checked the gas pedal cable. I’m running out of ideas, so I need your tips and suggestions.

IH8MUD · Cmas · 5 Nov 2026

A couple questions on adjusting valves without starting engine: 1) With a 46mm socket on the crankshaft pulley nut, should I be able to turn the engine into position by hand using a 1/2 drive breaker bar and one or more spark plugs removed? 2) Having trouble eyeballing and accessing the timing mark/line in the bell housing sight hole. Any suggestions for making this easier to get valves in proper position? Can I remove the distributor cap and look for the pointing position of the rotor... Read more

For B Bodies Only · moparedtn · 5 Nov 2026

Probably been beat to death on here, but I need some help in diagnosing an issue Fred has had for some years now... Symptoms: At part-throttle cruising (a little load on engine, less than highway speeds, over 2000 RPM) there is a slight, yet very distinct, "jitter" in the engine. Pretty sure it's ignition-related (but not 100% positive, of course) - just slight, perceptable "dance" it does, like really quick little surges, like it can't decide between two RPM points for the same...

So I’ve got this 89 240 in my shop atm. And for some reason injectors and spark only happens when the key goes from key 3 to key 2 (run) No injector pulse while cranking and no spark while cranking I’ve tested ignition stage module fuel Ecu ,EZK,CPS, Coil started with all the pin from the ignition switch falling out then repining that. I’ve used Daves schematics. But mostly the Bentley book for the diagrams. I’ve traced almost every wire in the system still no luck. Also all the parts... Read more

…at 40,700 miles, as per owner’s manual. The tips look like they could have gone one heck of a lot longer/further, but I suppose there’s a concern that the ceramic insulator is the weak point.

CivicX · Rafael Gomez · 30 Oct 2026

Hello everyone! My car is 2021 Honda Civic EX 1.5 L Turbo. I was wondering what is truly required and what is recommended to complete at 100K miles. I know transmission oil replacement, Oil and filter , Brake fluid . Spark plugs all required How about coolant drain and replace is that really required? I have never done that. How about a valve cleaning if I have never got that done before ? How about valve clearance checks? I still have great mpg around 42 mpg. How about serpentine belt... What is 100,000 miles required maintanence
