Got an old 87’ Corvette and gave her a really well-deserved refresh. Took over 6 months of on-and-off hard work, but I’m so happy with the result!

Hello everyone! For some context, I’ve just finished up my first engine build ever. I took an old beat up L98 from a 1987 Corvette and refreshed it. I put in new gaskets for the entire engine, new rings, push rods, rollers, freeze plugs, etc. I also got the heads resurfaced, which it really needed since they were very warped apparently

Today, after 5+ months of extremely meticulous and hard work, I finally started her up, and I couldn’t be happier. It’s my dream car and a beautiful engine, I’ve had a grin ear-to-ear for the past 7 hours now. I’m making this post in the hopes that someone who knows more than me can tell if the engine sounds good or not. At the moment it’s not properly timed, again, it was my first time starting it. But I will be timing it properly ASAP! And if you couldn’t tell by the deafening sound its had the exhaust pipe removed since I still need to do some transmission work, so that’s why it sounds like a tractor

Any advice is seriously appreciated! Thank you for reading!

Hello, I hope you’ve all been having a great day so far. I have a 1987 L98, and I was finishing up my engine and noticed on the passenger side of my throttle body there’s a small tube in between what I assume are two coolant passages going into it. What goes into it? And where does it connect to? Is it related to EGR? Would really like to know just to have peace of mind. Thank you for reading!

Washed my hair and noticed that it seemed really thin in this section, is this just because of my hair being all clumped together after showering or is this an early sign?

Hello! I’m preparing to finally install my engine ( L98 ) and was left absolutely dumbfounded by this threaded hole on the drivers side of the engine. ( The hole to the left near the freeze plug. ) It goes into the block, and I don’t know if it’s a sensor that goes there or maybe some kind of bolt? Idk! But even if it was a sensor, I can’t find one that fits in this hole anywhere

If anyone can help me here I would seriously appreciate it, I can’t find any information online on this

Hello, I’m currently re-assembling my engine and have reached the point where I’m installing the top end stuff that goes on the intake manifold

This specific engine that I bought had the EGR system completely deleted, which I hear is both good and bad, I’m not sure honestly. Less wires and clutter in the engine bay is definitely a big plus though

But my question is, if I wanted to do a block off on this EGR Valve can I just weld the hole on the tube thingy shut or do I need to do something else? Should I just buy an EGR block off plate instead? Thank you for reading!

Hello all, I’m currently still in the process of assembling my L98 engine for my 1987 corvette. Ive reached a point in the assembly process where all that’s left are things like sensors and things of that sort, I’m almost there! But I’ve hit a few stumps and have a few more questions before I can fully assemble it. I decided I’d ask here since online there’s barely any information on what I’m looking for..

My first question is, what is this metal hook thing near the dipstick tube? I know that it’s supposed to go here. But I cant for the life of me figure out how it should be positioned or what it’s supposed to do.

Second question is, was this little metal clip installed correctly? I’m pretty sure it’s a ground so really wanna make sure it’s on right

And my last question is the most important one I’d say, why does my intake manifold only have 2 holes for sensors in the front when the other engine that I’m ripping parts has 3?

Any help is seriously appreciated, and thank you all for the previous help! I would not have gotten this far without it! Thank you for reading

No clue what it is but it’s huge!! I live in the middle of Florida near the lake. The bug is about the size of a really big cockroach, found it outside hanging onto a few strands of my tiki umbrella. Really wanted to take a closer photo but I got scared since it seems like the dude could come flying at me. I love bugs so I really wanna know, what is it???

Hello again! I just finished the grueling process of removing the L98 engine from my 87’. Unfortunately, in the process, thanks to shocking amounts of stupidity and ignorance I may have broken a thing or two or three. And as for the engine, I’m gonna be adding another L98, but this new one’s squeaky clean. this one was junk but I will be reusing some parts here and there.

It was my first time ever doing this sort of thing so it’s honestly not the worst outcome! I’ve attached the photos to this post👍

First photo seems like a cable of some sort, absolutely snapped in half. There were around 3 if I remember correctly on the side of the throttle body

Second photo are some prongs on what seems to me like a sensor that got bent all the way down..

Third photo seems like a wire of some sort got clamped? Not sure if this is apart of the EGR system but it was around the rear of the engine near the distributor. The previous owner added an EGR block off plate and all sorts of things things that go along with it.

Fourth photo I genuinely have no clue where it came from. I’m drawing a blank here. I always mark and organize parts when I take them off so I must’ve missed this one. I don’t know. Any help at all is seriously appreciated, thank you for reading!

Hello all! I’ve been working on changing the engine on my 1987 Corvette since the old one was very bad for lack of a better word. Previous owner was not very attentive of the car.

Thing is though after getting down there I noticed a transmission fluid leak coming from this sensor? Why is this happening? Should I buy a new sensor or is there something I should do that could stop it? This is my first time working on one of these cars so I’m still getting familiar with it. Transmission is a 4L60, any help is seriously appreciated!

I’m currently working on assembling an SBC 350. It’s an L98 for a Corvette, and I’m in the middle of finally installing the lifter rollers, but I just happened to notice halfway through that they have a small hole on one side? What does it mean?

The hole points to the side, so it could only point left and right. Where is it supposed to go? Facing the other roller? I couldn’t find any info on it online so thought i’d ask here, thank you so much for reading!

First time working on an engine. I’m currently working on a SBC 350, an L98 if you need to know. And I’m in the process of installing a new front main seal but it for the life of me will not go in all the way. I’m using a 2 inch PVC to get it in. As it is now, it slightly protrudes out and I’m not sure if that’s as much as it goes or if it’s not seated all the way. Any help is seriously appreciated!!

Hello! I’m currently working on changing the head gaskets on my 1987 Corvettes L98 engine. I still have to clean the piston walls and etc, I was just trying them on. I’m using a head gasket from a FELPRO engine gasket kit, but it just seems off? I’ve never done head gaskets before, so I can’t tell if it’s intentional or not, but it doesn’t sit on the mating surface 100%, and had a hole going into the intake manifold area for some reason? Is this intentional or did I buy the wrong set? Any help is appreciated!
