Well, what kind of fluid is it? Coolant? Oil? Sometimes oil can be used for long term storage, or it could mean the oil control rings failed before the engine was pulled. Coolant would mean failed seals and rusted housings/irons/rotors.

yep fluid in the chamber is never a good sign.

from what i was told it's coolant

Coolant o-rings have failed. This could be from a few reasons:

1. Corrosion in the coolant passages
2. Warped rotor housings from overheating

Either way, it's a rebuild. The main difference will be what engine parts need to be replaced during the rebuild. You won't know that until the engine is disassembled.

go to rotaryressuerection.com in the teck section they have a write up for an easy fix and they say it works

If the engine has been sitting with coolant in the chambers, it has most likely rusted to the point of being useless. The irons and rotors will not be happy to sit in a pool of coolant. Inspect it through the exhaust ports with a light, see if it turns over by hand, and test compression.

oem. get em from mazdatrix or atkins or similar. but you better be ready for a task when it comes to rebuilding. youre prolly gunne need to replace other stuff. prolly will be easier for a tii swap

you really think so more or less how long will a rebuild take if i have all parts ready for the rebuild

the rebuild doesn't take long at all. it's the tear down, checking to see what parts will need replacing, and the cleaning and prep work needed that's time consuming. hard to give an actual time period cause if ur doing it urself, it'll depend on just how much time u will have to spend working on it between ur job and other things like can throw at u. but i'd say a week or two at least. then u have to take into consideration problems u may run into during the process like waiting on parts to arrive or broken bolts, etc. not to mention if u want to get any porting done.

sound good im on a 4 month time period well im more then likely going to need seals o rings maybe rotors and housing know of anyone they maybe selling housing and or rotors and how much do they go for both used and new
