LS3 head from jasper engines with 7k miles

Piston left the chat still haven’t looked at crank wonder what happen maybe something got through have no words.. still haven’t looked at the cylinder walls got pretty late last night

Hi, so i installed new rod bearings for my Hyundai Veloster 1.6 gdi from 2011.

I did the measure with plastigage and 3 of the cylinders were between tolerances except the fourth one.

My clearance from the manual states 0.032 - 0.052mm
I measured the following=
Cilinder 1 0.050mm
Cilinder 2 0.038mm
Cilinder 3 0.038mm
Cilinder 4 0.025mm

Should i send it or hell nah?

Im kinda tight on time and money so idk what i should do best

I have a small engine from a line plane i just bought. I have been trying to rebuild it and get it running. I think i damaged the glow plug. i dont know where else to ask! Please help anyone!!

Hello all, can anyone help me identify this ticking noise? It’s a 283, doesn’t seem to go away when warm. Does this sound like lifter noise or bottom end noise? Thank you.

So I’m being given a 427 that came out of a late 70s asphalt modified. It is currently just mostly complete short block, has an unknown solid roller cam, pistons with a decent dome. Looks in decent shape but needs a refresh after sitting for 40 years. I have a 59 Edsel I was given for free that’s in ok shape. Looking to shoe horn this engine into there as cheap as possible not necessarily looking to be the fastest just more of a fun cheap car. Been looking for cylinder heads for this engine, have about an $800 budget for a pair of heads what would you recommend?

There’s a decent set of 049 heads by me for $250 or should I look for closed chamber stuff?

This is my first engine rebuild on a Honda B18c1. I noticed the connecting rod #4 at the wrist pin is discolored. The wrist pin moves freely and smoothly in the connecting rod. Is it still okay to use? Pic 3 is what cylinder 1, 2, 3 look like. Thanks in advance for your opinion.

Im rebuilding/refreshing this small block chevy its a 1970s ish block and heads rebuilt by Jasper a while ago my grandpa had it in his Biscayne for about 20k miles. Tearing it down to put in new valve stem seals I found these cracks from where new valve guides have been pressed in. THE CRACKS DO NOT GO ALL THE WAY THROUGH. They are only on the surface where it was drilled thin and new guides were pressed in but i am curious if it will be good to send it anyways. Im not too sure how it ran/if it smoked before since it has been out and non running for quite a few years.

Planning to start assembling an lq4 tomorrow, but I’d like to get some paint off of my aluminum heads so I can shine the aluminum up (paint looks ghetto to me)

What can I do in the next 20 or so hours to atleast remove paint enough to shine them down the road once engine is assembled

So I bought a ‘77 K10 last month and it runs good but there’s a noticeable vacuum leak from where the carb meets the intake. The carb is a Holley Street Denon 625 and they used the stock intake, which I’ll include a picture of here. The gasket is in good shape, but it appears the adapter plate they used doesnt come back far enough to fully cover this recessed part of the intake, causing the leak. Can someone point me in the right direction of getting the right adapter plate to make this work? I saw my local advance auto parts has an adapter kit, but it’s likely the same adapter they tried using on the bottom. I’ll post pics of the carb later.

Trying to find the best rockers for this build that don't break the bank. Any suggestions?

might be a dumb question but its my first time in a motor so i have nothing to compare to, but im assuming i need a new valve and lapping wont fix the issue? i have a spare motor i can pull valves out of since 3 look like this

Hey everyone I recently made a post about building my 5.3. I wanted to come with some updates.

The seller ultimately ghosted me after I pressured some more on why the block was spray painted. I ended up going to an engine shop and bought a 06 5.3 with 98k miles for 600. They also had an SS engine and a 6.0 but I wasn't trying to spend that much plus most of the parts I have for now are for the gen 3 build. Edit: yes that is a chip bag being used as the oil cap

i don't remember sticking them in this way and have no idea how this came to be. it drives fine, loud whirring noise though. not sure it's the source of the noise, with a stethoscope it's loudest when i put it on the intake manifold.

but anyway, back to the cams, i already sent them, but i don't know how long they wil last. there's no damage on the head itself, which i find odd. no symptoms that i can figure.

any theories?

I recently pulled the motor in my deville to do head studs. I just assumed ignorantly it was a head gasket due to losing compression entirely between 2 neighboring cylinders. Should have done a leak down but oh well it’s getting bulletproofed now. After getting it on the engine stand and pulling the valve cover on the rear bank I immediately noticed 4 of the rockers were entirely dislodged, one on each intake cylinder. On the front bank there were 5 dislodged, all intake as well. Surprise surprise the two dead cylinders had no rockers on their intake valves. The car was from an estate sale non running I put a fuel pump in it started right up and drove it home (5 mile drive). I left it idling to run some fuel through it since it had been sat for many years. After about 30 minutes it started misfiring, no overheating good oil pressure. I killed it and it had a noticeable gallop and would not run afterwards. What could possibly cause this car to throw 9 rockers this way? Could one slack adjuster collapsing cause others to drop pressure? I’m very confused how it’s only the intake valves on both banks. Surely it did not throw 9 simultaneously. I suppose it could have already dropped a few before I got to it and it ran okay off one valve per cylinder until it finally kicked those 2 off on the neighboring cylinders. Is the oil supply for the intake side adjusters tied together on both banks? Sorry for the long ramble, I’m stumped on what could’ve caused this.

Old head failed. Replacing. Using a lisle scrap thingy. Anyways head look good back together? Some scratches but I don't think actual scratch as I don't feel anything with finger nail. Thought soak in like acetone to get it cleaner for a bit. Also should I spray cylinder with wd-40. Once head is ready I need to order actual head and be a few weeks out. Thoughts prayers? 2014 ram 2500 with about 170k on it

Basically my EA888 Gen3 engine was recently diagnosed with damaged pistons. Today I made some photos from every cylinder, and now I would appreciate those who know this stuff help me understand how bad it is, and what can be realistically done about that.

Had an over heating issue on a 2004 3.4L Grand Am. Held 16psi for over 20 minutes but when driving on the free way it would peg the meter. Down an average 35-40mph road it would sit at 200, had all new radiator, water pump, reservoir, t-stat and hoses done on it before I picked it up. Pulled the heads expecting a cracked head gasket as there was signs of water in the oil but nothing leaking or coming out the tailpipe.

Well as you can see a clogged passageway casued issues and something eroded the head material right next the the cylinder wall sealing area for a head gasket. I am confident in my welding abilities to fill and my local head shop to get them flattened, but would you? I am certain my local yard or fb marketplace can yield a motor or a set but I am also not trying to sink lots of money into my $500 car.

I am building a Ford 351w. When I got the block back from the machine shop I noticed a plug installed on the oil passage behind the timing cover. This is on the driver side. I didn't think much of it until I went to install the fitting for the oil pressure pressure sender. They put some sort of sealant on it and it is not coming out. I've tried impact, both the hammer variety and a impact gun. I'm hesitant to put heat to it because of the gaskets near it. Is that my best path? Or does anyone have recommendations?

I have left out my 240SX camshafts, they didn't get rained on but because the humidity, they have some minor rust. Would using the gray scotch, bright, be okay. I see. Conflicting information on youtube. I just wanted to ask people who actually built engines.

I am working on my own personal vehicle, 1995 Mitsubishi Mighty Max with 2.4 4 cylinder. The truck had developed a head gasket leak a couple years back and it took me a while to source all the parts. I wasn't able to save the head so I ordered an identical replacement. I am working on removing all of the gasket material before checking for straightness. I am worried about the light rust in the cylinder walls and wondering if a light hone might be good.

I probably should have just yanked the block and gone through it as well but I procrastinated this project for 3 years and I would like to get it running again.

Welp! The 6.4 tear down is getting interesting gents. Definitely need the 🧠 brain trust on this one… anybody got a “trick” for pulling a cam bearing off of a cam still in the block? Also, there was no main bearing on one of the crank journals (how?! Idk) does the crank look salvageable? I was trying to reuse the stock internals so I could learn and make mistakes on the “cheap” stuff BUT obviously that’s no longer an option. Already looking at forged internals 😩
