Hi im new to rebuilding and putting back my engine. i got the vitara 75.5 pistons, eagle rods for my d16z6.
i sent it first to get bored out extra .5 to fit the pistons. i didn't know that i had to get the block notched and gridle???


Please help i want to know that if its still safe to get the block notched at a machine shop. the bore is already cleaned and shiny. if i get it notched and all the grinded metal contaminate the clean bores??? metal shavings etc.
dam the bore is already good.

dam i need help.. am i messd up??
im sure i will send this engine to the machine shop. the engine is all together assembled but can't turn bc the dam notching required??


am i messed up.
should i leave it like this and send it to a machine shop.
ididn't know ive had to get it notched first pls let me know?????


any one bored it out first then notched later???????????
scared the clean spec bores will get contaminated????

 

Settle down. The notching is at the bottom and the pistons will never go that low. It will be fine. You can even notch it yourself with a dremel.

 

I dont want to do it myself. But the hard part is that its put together and the bearings/rods/pistons all in. If i send to the machine shop do i leave it all in and they measire to cut it. I dont want to remove it again. And im scared for the main metal particles will it damage anything . The bore is fresh and clean. the shop have to grind the gridle also

 

The girdle can be taken off and ground. You could leave the pistons and rods in it, just disconnect them from the crank and let them slide down a bit. Then push the rod over and out the way and get in there with a dremel. You don't have to take much off. As far as metal shavings just air hose it really good. It's not gonna kill the hone.

 

Dremel grit doesn't sound good. Make sure and stuff some towels in there to catch that mess. Mask it off good... the possiblitly of a little dremel grit and metal in an oil journal would keep me awake nights.

 

Dremel tool with proper metal grinding bit NOT a sanding disk

 

okay i got everything still in the block crank gridle, rods, pistons. etc.

my question is that that i plan on sending it to the machine shop to get them notched.
can the bearings be still reused if i remove them????

do i leave the block assembled and send it to the shop or re assemble it???

 

These are questions for the shop. As a matter of fact this whole thread started with a question you SHOULD HAVE called the shop about. It's a DIY project but since you're not doing it yourself you need to be informed by the people performing the work. Not a bunch of strangers on a forum with conflicting information.

 

I'm wondering why has it been so long and op still asking the same basic question. Will it be ok? You have a block with ZERO MILES. It can be taken apart and put back. JUST DO IT ALREADY

 

just take the pistons out and do it the right way and make sure its clean.... any shop is going to do it this way.... i ended up using a carbide bit to knotch mine.... the grinding stones take FOREVER.....

 

okay im thinking on notching the block/gridle by myself. im thinking on getting a dremel set. what dremel tool would best suit for this job...

 

I used a pos $7 harbor fright dremel and a fine metal bit. it took a while but got results

 

did it work with the block notching too????
how long did it take you to do the block notching...

 

Who cares how long it took?
He said it took awhile.
If you're not going to take it back to the machine shop to even verify it needs notching or have them do it then you better get your tools handy and set aside some time.

 

At least cover/remove your bearings while you're grinding on the girdle to avoid contamination...

 

I had shop rags covering everything but the section i was working on, i took them off for the pic tho

 

okay one more thing i got a dremel 4000 brand with some other flex attachments. will this work good??

i saw your picture what kind of dremel bit did you use????
what can i use for notching it?? and later polishing it. aluminum bits etc??? or no???

need some info before i go ahead..

thanks...

 

i did mine with a flexible line attachment to a drill press with a carbide bit. much bigger scale then the dremel. you have to be careful as the bit will cut the metal quickly... i also used the grinding stones but that took a while...you can use a dremel as shown above. i would use carbide metal bit...you can always use the crbide bit to get the majority knotched then use a polishing stone to fine cut the last bit as it will also polish the final result.
