compression

Hi I’m new to the group, I own a 2005 4th gen 4runner limited with the 2uzfe. I’ve owned the car going in 6 years with no issues other than an intermittent P0430 which usually went away so I ignored it. 5 months ago I replaced all the spark plugs with oem from the dealer in an attempt to improve...

The 3FE is factory rated at 155 horsepower and 220 ft lbs of torque, the 2F is rated at 135 horsepower and 200 ft lbs of torque. I understand that the 2FE bumps compression, but how much more power/ torque would it make over a 3FE?

I have a 1973 f engine with very low compression thinking of looking into a gm straight 6 or v8 I have a 3 speed on the tree with vacuum on original chassis and also have a 4sp from on a 1973 chassis at this point looking for cheapest option to get on the road and ls swap down the road...

The compression values for cylinders 1-5 were between 100 and 125. But Cylinder 6 was 40. So I took the head off and had it reconditioned by a shop and put it back on - hoping it just needed a valve and seal job/new gasket. Put it all back together and compression values for 1-5 are somewhat...

Recently as in, in the last year, the top end on my 3vze was taken to a machine shop and surfaced by the PO's. Not to say they did a s***ty job but I have had to redo every single other fix theyve done since buying this 4runner in april/may. It was pretty clear when buying it but mostly a...

Hello, I have replaced my broken head with a new head and reconditioned bits done by a specialist. I have put everything together but pressure readings are on the low side from what ive read. Ive got 420psi, 350psi, 350psi and 360psi. Did i mess it up bad or should i just crack on and not worry...

Anyone have one? would be willing to rent or purchase. Thanks Mud

I'd like to have my 1HD-FT engine tested when I have it shipped back from Cape Town to the UK in the next few weeks, as I'm looking to sell it. There's a little black smoke but nothing crazy. It's done about 190k miles. Can anyone suggest somewhere in the UK where I could get it compression...

Hello all, Long time reader but this is my first time posting. I picked up a new toy this week (91 fj80, 170k original miles, 3FE). It had been idling extremely rough and in order to keep it from stalling you had to give it a little gas... with no OBD 1 codes First thing was to check all the...

Hey mudders. Just thought I’d ask for some people to weigh in on this. I’m not one for snake oils or quick fixes. I am not suggesting this is a remedy for any maintenance or getting around fixing a real problem ie head gasket or putting new rings on pistons. I was wondering if this would be...

Hello, I have a polished aluminum intake pipe for the FJ62 or FJ80. Never been installed. The company the produced this intake pipe doesn't seem to be in business anymore. Asking $100.00 plus whatever shipping. Please PM me

I've spent a couple hours searching for an answer to my question. I hate to ask (because I'm sure it's already been answered), but I can't find the answer, so here goes. #1. I'm attempting to set the timing on my '73 F engine. My flywheel has the metal ball, but no other timing marks. I...

Hi All! I've been a reader on this forum since June 2016 when I picked up my 1994 FZJ80, but this is my first post. Apologies in advance for the lengthiness, but I'm sure the more information I provide, the better you can advise me on moving forward. I got my LC from a local guy who said it had...

Ok, I have a situation with my truck and I need some advice and opinions. I've gotten some, but since I have a bit of time before making a final decision, thought I'd get some more. I have a 1980 BJ40 with a B engine. I've only owned it for about 3 years, and it was not exceptionally well taken...

I figure I must be doing something wrong.... I just purchased a 91 with the 3FE motor. When I went to have it smogged prior to transferring title it failed. I went to do a minor tune-up (plugs, wires, cap, and rotor) and figured while I was at it I'd go ahead and check the compression. While...

I purchased this from my wife's sister in 2000 with 90k miles. It was my DD until April '14, then only driven 1-2x month on weekends. It has always been a great vehicle, but burned/used oil, slowly increasing thru the years - eventually having to add a quart every 600-700 miles. No leaks, some...

I'm putting together a batch of parts and tools to do a bit of inspecting of my engine in the near future; specifically valve clearances, compression test and having a look at the state of the injectors. Since there's no glow plugs on this more, i get to pull a lot apart In the process. In...

Hello mudders, I have a 77'FJ40 that up till a couple weeks ago ran great, now it seems like to have hardly any power at all. i have checked several things but nothing really stands out. After alot of reading on this forum I came to the conclusion I may have a blown headgasket. i have done a dry...

So as the title states, I have to do a test on a 4.6 rebuild with 6K on it. It has a terrible miss and seemed to be running on about half of the cylinders the last time I limped it home. I did a search about numbers I should hope to see, but would love any additional wisdom. I can't really rev...

Hi All - I finally confirmed what I was thinking all along, my stock (and project) '70 FJ40 F155 engine has low power. Ran a dry compression test and got 90/80/80/80/85/90. I know normal is 140-150. My question is how to proceed? I heard people having success removing the head for milling...
