# 3804529 Longblock Core | Genuine Volvo Penta Part

## 🔧 Product Description

This is the core deposit line for remanufactured longblock 3801529, not a standalone item. Volvo Penta supplies that unit on an exchange basis: the deposit is charged alongside it and refunded once the old longblock is returned. Ordered on its own it buys no fittable part.

## ⚙️ Key Features

-   Core deposit line, paired with remanufactured longblock 3801529
-   Refunded when the old unit is returned
-   Not a standalone item

## 🔌 Function

Covers the refundable deposit on the old unit being exchanged, rather than supplying a part.

## ⚠️ Common Signs of Failure

-   This is a deposit line and has nothing to fail in itself; the signs below are what normally condemns the longblock being exchanged
-   Blue smoke and heavy oil consumption that no amount of top-end work will cure
-   A deep knock from the bottom end that hardens under load, or oil pressure falling away once hot
-   Compression down across several cylinders, with hard starting, lost power and blow-by from the breather
-   Coolant and oil mixing, or metal glitter found in the oil and filter on strip-down

## 🛠️ Service Notes

-   Order this together with 3801529 - the deposit on its own supplies nothing that can be fitted
-   The deposit is refunded once the old longblock is returned to us

## 📦 Condition

-   Refundable core deposit - not a physical part
